* fix: use render client id to track deleted render process hosts
Instead of relying on OS process id, which may not be unique
when a process is reused, we rely on the renderer client id
passed by the content layer when starting the renderer process
which is guaranteed to be unique for the lifetime of the app.
* fix: store context id as int64_t
Ensuring that it doesn't wrap easily with a large number
of context creation on some malformed web pages.
* fix: use OOIF for webview tag
* fix: do not call GetNativeView for webview
* fix: OOIPF webview's WebContents is managed by embedder frame
* fix: guest view can not be focused
* fix: clear zoom controller when guest is destroyed
* fix: implement the webview resize event
The webview is no longer a browser plugin with the resize event, use
ResizeObserver instead.
* test: disable failed tests due to OOPIF webview
* fix: embedder can be destroyed earlier than guest
This happens when embedder is manually destroyed.
* fix: don't double attach
* fix: recreate iframe when webview is reattached
* fix: resize event may happen very early
* test: some tests are working after OOPIF webview
* chore: remove unused browser plugin webview code
* fix: get embedder via closure
When the "destroyed" event is emitted, the entry in guestInstances would be
cleared.
* chore: rename browserPluginNode to internalElement
* test: make the visibilityState test more robust
* chore: guestinstance can not work with OOPIF webview
* fix: element could be detached before got response from browser
After after using `processId-contextCounter` as contextId, it may happen
that contexts in different WebContents sharing the same renderer process
get the same contextId. Using webContentsId as part of key in
ObjectsRegistry can fix this.
