Reviewed by Tim Nguyen.

When the system status bar hides during media playback, this updates the UIWindow's safeAreaInsets
property, which propogates into web content by resizing the content area of the WKWebView.

Avoid this resizing by providing a minimum value for the safeAreaInsets.top, via overriding the
WKFullScreenViewController's -additionalSafeAreaInsets method.
