The problem here is that the new orientation API introduces the concept of a document's orientation lock and the algorithms tell us when it's set. When the active top-level browsing context changes, we need to update the screen orientation according to the document's orientation lock (currently this isn't set when we use the old API which causes an orientation unlock every time the browsing context gets activated). This is in contrast to the old behavior where orientation locks would persist across browsing contexts until explicitly changed or unlocked.

In this patch, I've added code to update the orientation lock on browsing contexts even when using the old orientation API so it behave a bit better with the new orientation behavior. In addition, I've disabled updating the orientation when activating app docshells so that it preserves old API behavior. I did it because I noticed that apps can activate multiple docshells that look like "top-level" browsing contexts and may cause an unintentional orientation unlock following an orientation lock. Also, the new behavior can causes visual weirdness because in some cases we don't want to change orientation between switching apps, but with the new API, when the next app is loaded, we start by unlocking the orientation per spec, then the app locks the orientation. This results in a brief moment where the orientation changes, then changes back again.
