In most browsers, clicking links with the Alt key has a special behavior, for example, Chrome
downloads the target resource. As with other modifier keys, the router should stop the original
navigation to avoid preventing the browser’s default behavior.
When users click a link while holding the Alt key together, the browsers behave as follows.
Windows 10:
| Browser | Behavior |
|:-----------|:--------------------------------------------|
| Chrome 84 | Download the target resource |
| Firefox 79 | Prevent navigation and therefore do nothing |
| Edge 84 | Download the target resource |
| IE 11 | No impact |
macOS Catalina:
| Browser | Behavior |
|:-----------|:--------------------------------------------|
| Chrome 84 | Download the target resource |
| Firefox 79 | Prevent navigation and therefore do nothing |
| Safari 13 | Download the target resource |

The type-to-value conversion could previously crash if a symbol was
resolved that does not have any declarations, e.g. because it's imported
from a missing module. This would typically result in a semantic
TypeScript diagnostic and halt further compilation, therefore not
reaching the type-to-value conversion logic. In Bazel however, it turns
out that Angular semantic diagnostics are requested even if there are
semantic TypeScript errors in the program, so it would then reach the
type-to-value conversation and crash.
This commit fixes the unsafe access and adds a test that ignores the
TypeScript semantic error, effectively replicating the situation as
experienced under Bazel.

Previously, localized strings had very limited or incorrect source-mapping
information available.
Now the i18n AST nodes and related output AST nodes include source-span
information about message-parts and placeholders - including closing tag
placeholders.
This information is then used when generating the final localized string
ASTs to ensure that the correct source-mapping is rendered.

The `MessagePiece` and derived classes, `LiteralPiece` and `PlaceholderPiece`

The `TagPlaceholder` can contain children, in which case there are two source
spans of interest: the opening tag and the closing tag. This commit now allows
the closing tag source-span to be tracked, so that it can be used later in

The `R3TargetBinder` accepts an interface for directive metadata which
declares types for `input` and `output` objects. These types convey the
mapping between the property names for an input or output and the
corresponding property name on the component class. Due to
`R3TargetBinder`'s requirements, this mapping was specified with property
names as keys and field names as values.
However, because of duck typing, this interface was accidentally satisifed
by the opposite mapping, of field names to property names, that was produced
in other parts of the compiler. This form more naturally represents the data
model for inputs.
Rather than accept the field -> property mapping and invert it, this commit
introduces a new abstraction for such mappings which is bidirectional,
eliminating the ambiguous plain object type. This mapping uses new,
unambiguous terminology ("class property name" and "binding property name")
and can be used to satisfy both the needs of the binder as well as those of
the template type-checker (field -> property).
A new test ensures that the input/output metadata produced by the compiler
during analysis is directly compatible with the binder via this unambiguous
new interface.

This commit adds `ngDevMode` guard to throw some errors only in dev mode
(similar to how things work in other parts of Ivy runtime code). The
`ngDevMode` flag helps to tree-shake these error messages from production
builds (in dev mode everything will work as it works right now) to decrease
production bundle size.

If a type has been renamed when it was exported, we need to
reference the external public alias name rather than the internal
original name for the type. Otherwise we will try to import the
type by its internal name, which is not publicly accessible.

A recent change to `@angular/localize` brought in the `AbsoluteFsPath` type
from the `@angular/compiler-cli`. But this brought along with it a reference
to NodeJS typings - specifically the `FileSystem` interface refers to the
`Buffer` type from NodeJS.
This affects compilation of `@angular/localize` code that will be run in
the browser - for example projects that reference `loadTranslations()`.
The compilation breaks if the NodeJS typings are not included in the build.
Clearly it is not desirable to have these typings included when the project
is not targeting NodeJS.
This commit replaces references to the NodeJS `Buffer` type with `Uint8Array`,
which is available across all platforms and is actually the super-class of
`Buffer`.

This commit upgrades all dependencies in `aio/aio-builds-setup/scripts-js/`
to latest versions and also includes all necessary code changes to
ensure the tests are passing with the new dependency versions.
In particular:
- We ensure `nock`'s `Scope#done()` is not called before receiving a
response to account for a breaking change introduced in
nock/nock#1960.
- The use of `nock`'s `Scope#log()` method was removed, because the
method is no longer available since nock/nock#1966. See
https://github.com/nock/nock#debugging for more info on debugging
failed matches.

Previously, the compiler was not able to display template parsing errors as
true `ts.Diagnostic`s that point inside the template. Instead, it would
throw an actual `Error`, and "crash" with a stack trace containing the
template errors.
Not only is this a poor user experience, but it causes the Language Service
to also crash as the user is editing a template (in actuality the LS has to
work around this bug).
With this commit, such parsing errors are converted to true template
diagnostics with appropriate span information to be displayed contextually
along with all other diagnostics. This majorly improves the user experience
and unblocks the Language Service from having to deal with the compiler
"crashing" to report errors.

The template type-checking engine includes utilities for creating
`ts.Diagnostic`s for component templates. Previously only the template type-
checker itself created such diagnostics. However, the template parser also
produces errors which should be represented as template diagnostics.
This commit prepares for that conversion by extracting the machinery for
producing template diagnostics into its own sub-package, so that other parts
of the compiler can depend on it without depending on the entire template
type-checker.

`tView` that is stored on a component def contains information about directives and pipes
that are available in the scope of this component. Patching component scope causes `tView` to be
updated. Prior to this commit, the `tView` information was not restored/reset in case component
class is not declared in the `declarations` field while calling `TestBed.configureTestingModule`,
thus causing `tView` to be reused between tests (thus preserving scopes information between tests).
This commit updates TestBed logic to preserve `tView` value before applying scope changes and
reset it back to the previous state between tests.

Previously this package was installed in the default `dependencies` section
of `package.json`, but this meant that its own dependencies are treated as
dependencies of the main project: Babel, for example.
Generally, $localize` is not used at runtime - it is compiled out by the
translation tooling, so there is no need for it to be a full dependency.
In fact, even if it is used at runtime, the package itself is only used
at dev-time since the runtime bits will be bundled into a distributable.
So putting this package in `devDependencies` would only prevent libraries
from bringing the package into application projects that used them. This
is probably good in itself, since it should be up to the downstream project
to decide if it wants to include `@angular/localize` at runtime.
This commit changes the default location of the package to be the
`devDependencies` section, but gives an option `useAtRuntime` to choose
otherwise.

The HTML parser gets an element's namespace either from the tag name
(e.g. `<svg:rect>`) or from its parent element `<svg><rect></svg>`) which
breaks down when an element is inside of an SVG `foreignElement`,
because foreign elements allow nodes from a different namespace to be
inserted into an SVG.
These changes add another flag to the tag definitions which tells child
nodes whether to try to inherit their namespaces from their parents.
It also adds a definition for `foreignObject` with the new flag,
allowing elements placed inside it to infer their namespaces instead.
