Rotating recreates the Activity and the GeckoView, so we need to hook the new GeckoView up to Gecko. This now draws the page after rotation, but there's several question/issues that still need to be sorted out: 1) With this patch, I've noticed that after rotating/zooming, touch events are misaligned with where I'm actually touching on the screen. 2) We call GeckoAppShell.registerEventListener() with 'this' as the listener, so the destroyed GeckoView is leaked whenever we rotate. We'll need to figure out a way to unregister these listeners (onDetachedFromWindow?) or decouple them from GeckoView. 3) What happens when we receive events from Gecko while there is no view available (e.g., we're in the middle of a rotation, or we're in the background with "Don't Keep Activities" enabled)? With the current implementation, it's possible that the GeckoView client misses something like Gecko:Ready, and the application becomes borked.
