Subject: [PATCH] fix(dialog): present dialogs from the topmost view controller
 on iOS

Present each alert from the topmost presented view controller instead of the bridge
view controller, so a dialog appears above any view controller the app has presented
over the web view. UIKit refuses to present from a view controller that already
presents one, and the refusal has no error path, so the call never resolved.

If the walk stops at a controller whose presented child is still being dismissed,
reject the call instead of leaving it pending.

Closes #2404
