Remove fullscreen button on iPad if using a non Safari browser

Problem statement:

#219

Using fullscreen video on iPad + touch interactions + non-Safari browsers = video gets dragged around the screen.

This is fairly unusable for Pixel Streaming but it browser defined behaviour that can't be disabled it seems.

Additionally if you leave fullscreen from one of these non-Safari browsers on the iPad the video stream will pause and cannot be resumed without re-entering fullscreen mode because we hide the video controls.

Solution

Don't allow fullscreen button on these non-Safari browsers on iPad.

Test on iPad on Chrome = button is gone

This removes scroll bounce zone on iPad that is unhelpful for Pixel Streaming
