When a PlatformView is placed on top of another widget, say a button, the button won't receive hover events:

Stack(children: <Widget>[
  RaisedButton(
    onPressed() {
      print('onPressed'); // Taps are handled correctly.
    },
    child: Text('Hover or click'),
  ),
  Positioned.fill(child: MyPlatformView(...)),
])

Setting the hitTestBehavior of the PlatformView to PlatformViewHitTestBehavior.transparent didn't help.

Taps and other gestures are received by the button correctly. Hover is the only one that the button isn't receiving.
