<div>
<pre>When WKActionSheet is presented, it uses `[[_sheetDelegate hostViewForSheet].window rootViewController]` as the view controller to present from. But this doesn't work if the webview is actually inside a modally-presented view controller. This results in the sheet never showing and the following logged to the console:
Warning: Attempt to present <WKActionSheet: 0x7fbdac077a00> on <RootViewController: 0x7fbda8d7b340> whose view is not in the window hierarchy!
I imagine there's also issues with the rotation behavior, since it looks like it's supposed to dismiss itself and re-present after rotation.
The correct fix is to replace -hostViewForSheet with a method that returns the host UIViewController instead, but if that's problematic a quick fix would be to walk the presentedViewController chain to find the leaf controller and present on that (but this approach will have issues with view controllers that aren't fullscreen).</pre>
