Summary:
When using the new WKWebView class, if it is presented in a modal fashion, any long pressed links will not show the action sheet for choosing options as to how to handle the link. Instead, a message like the following is generated, "Warning: Attempt to present <WKActionSheet: 0x7fcd60572d10> on <ViewController: 0x7fcd60522c10> whose view is not in the window hierarchy!"

On iPad, if this happens and then a user rotates, the modal view is abruptly dismissed.

Steps to Reproduce:
0. Run the attached application.
1. Press the "Show Web View" button, and wait for the page to load
2. Long press on any element
(3.) if on iPad, rotate.

Expected Results:
The action sheet with options for link handling is correctly displayed. And if the device is an iPad, it rotates correctly without dismissing the content.

Actual Results:
No action sheet is presented on iPhone or iPad, however, the following message is generated, "Warning: Attempt to present <WKActionSheet: 0x7fcd60572d10> on <ViewController: 0x7fcd60522c10> whose view is not in the window hierarchy!". If the user is on an iPad and has rotated, the entire modal view controller is removed from the view hierarchy.

Version:
iOS 8 Beta 5

Also results in crash

If you then proceed dismiss the modal/presented view containing the WKWebView and then rotate, the app will crash.

Workaround

Apparently, the view controller is presented from the root view controller, not the nearest one with definesPresentationContext. So it helps to redirect the presentation from the root view controller:
