Lost Focus after Fullscreen exit

[Heddy147]

Bug Report

Problem

What is expected to happen?

After entering in fullscreen mode of a video then press the back button of android the fullscreen mode exits.
If you then press the back button again it should dispatch the 'backbutton' event.

What does actually happen?

After entering in fullscreen mode of a video then press the back button of android the fullscreen mode exits.
If you then press the back button again it does not dispatch the 'backbutton' event and closes the app.

Information

The focus does not requested after "hide the custom view". So the context of the 'backbutton' is not the WebView.

Command or Code

in #822 is fix to avoid this bug: #822 (comment)
In CordovaWebViewImpl.java:hideCustomView add engine.getView().requestFocus(); after engine.getView().setVisibility(View.VISIBLE);

We're currently facing an issue, which seems a bit related: In our case, if we listen for the "backbutton" event directly on the app start (after deviceready), it won't be called unless the user first clicks at the webview/app.

On older devices (eg. Android 6) this is working. On devices with Android 10 and 11, the user has to touch the app screen first, otherwise the "backbutton"-event won't be fired.

Yes, I have to click the webview/app, the focus is back to the webview and it fires the "backbutton"-event.

This looks like an issue with Splash screen plugin. I've had a similar issue that BACK button closed the app unless something was clicked inside the app. Once 'it got focus' the BACK button started working normaly, i.e. it was caught by my handler. Relevent issue from splash screen project.

Sorry for going off-topic a bit, i just wanted to clarify that BACK button not working at application start is a different issue.
