* 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
