Add support to configure hidding top bar and touch keys on MediaPlayerElement

That's actually not an issue. I just haven't found a good answer to this matter (or had the wrong key words to search for). I'm using the MediaPlayer element in my app. All is working fine, however on Android the app hides the touch keys and the topbar when entering the page where the MediaPlayer is on.

Is there a way to avoid this behaviour by setting a bool?

Thank you for helping out!
