Previously, only simple, single-slot transclusion worked on upgraded components.
This commit fixes/adds support for the following:
- Multi-slot transclusion.
- Using fallback content when no transclusion content is provided.
- Destroy unused scope (when using fallback content).
Fixes#13271
Previouly, whenever a new ServiceWorker update was detected the user was
prompted to update (with a notification). This turned out to be more distracting
than helpful. Also, one would get notifications on all open browser tabs/windows
and had to manually reload each one in order for the whole content (including
the app) to be updated.
This commit changes the update strategy as follows:
- Whenever a new update is detected, it is immediately activated (and all
tabs/windows will be notified).
- Once an update is activated (regardless of whether the activation was
initiated by the current tab/window or not), a flag will be set to do a
"full page navigation" the next time the user navigates to a document.
Benefits:
- All tabs/windows are updated asap.
- The updates are applied authomatically, without the user's needing to do
anything.
- The updates are applied in a way that:
a. Ensures that the app and content versions are always compatible.
b. Does not distract the user from their usual workflow.
NOTE:
The "full page navigation" may cause a flash (while the page is loading from
scratch), but this is expected to be minimal, since at that point almost all
necessary resources are cached by and served from the ServiceWorker.
Fixes#17539
`Object.assign` is not available in all supported browsers and one had to
provide a polyfill. This commit replaces `Object.assign` with the spread
operator (`...`), which TypeScript will transpile to ES5-compatible code.
