Previously, when trying to upload the build artifacts for a PR/SHA that was
already successfully deployed (e.g. when re-running a Travis job), the preview
server would return a 403 and the build would fail.
Since we have other mechanisms to verify that the PR author is trusted and the
artifacts do indeed come from the specified PR and since the new artifacts
should be the same with the already deployed ones (same SHA), there is no reason
to fail the build. The preview server will reject the request with a special
HTTP status code (409 - Conflict), which the `deploy-preview` script will
recognize and exit with 0.
Don’t show the side nav in mobile (not side-by-side) view when arriving or navigating.
Only show it by request.
The side nav should continue to appear in wide mode (side-by-side) when navigating from a marketing page to a guide page.
The implementation adds three plugins to the remark processor:
* remove support for code blocks triggered by indented
text - only gfm triple backticks are supported; and also adds support for
dgeni inline tags.
* ignore content within `code-example` and `code-tabs` elements. This prevents
the content being accidentally treated as markdown
* ignore dgeni inline tags, e.g. `{@link ... }` to prevent the content of
the links from being accidentally treated as markdown
* Fixes that `tsc-wrapped` stores invalid path separators in the bundled metadata files. Previous errors could have been: `Cannot find module '.corecoordinationnique-selection-dispatcher'.` (See https://github.com/angular/material2/issues/3834)
* Fixes failing tests on Windows. Now all tooling tests are green on Windows.
