In osx after return from videowidget fullscreen keyboard input is blocked

I tried using the qmediaplayer example and just adding a QLineEdit to check if I was able to receive keyboard events after return from full screen.
To check just do the same. Use the qmediaplayer example and add a QLineEdit in the last layout with the slider and play a file. Go to full screen and return from it. After return from full screen its not possible to type anything in the QLineEdit
