### Platform(s)
- Android

### Current Behavior
When the flag `FLAG_LAYOUT_NO_LIMITS` is set by another plugin (in my case, to make the navigation bar transparent) AND the `resizeOnFullScreen` option of `@capacitor/keyboard` is set to `true`, it sets the webview of the app to be about 9874px tall (width is, unsurprisingly, unaffected). My actual height is about 700-800px

### Expected Behavior
The WebView should still fit the screen, even if the `FLAG_LAYOUT_NO_LIMITS` is set

### Other Technical Details

### Additional Context
/

Start with the @capacitor/keyboard Android implementation and the resizeOnFullScreen handling, then reproduce the issue using the linked cap-screensize-issue-reproduction project. Check how FLAG_LAYOUT_NO_LIMITS affects the WebView height; done means the WebView remains within the screen when both settings are enabled and the Android behavior is covered by an appropriate regression test.
