Windows start blocking media by default (see the media.block-autoplay-until-in-foreground pref). If the document becomes visible from GetScriptHandlingObject(), we hand-rolled our own UpdateVisibilityState and didn't call MaybeActiveMediaComponents (which unblocks media playback). It couldn't call it there before since given content docshells used start as active, but now that they don't we can do that and fix the bug.
