Screenshots demonstrating issue
=== Overview ===
ContextAction menu is automatically dismissed when rotating from portrait to landscape mode in a Xamarin.Forms application on iOS.
=== Background ===
If there is an iOS ContextAction menu open while the phone is rotated, it seems to work correctly when rotating from from landscape to portrait mode but when rotating from portrait to landscape mode it is automatically dismissed. When rotating from landscape to portrait mode, the ContextAction menu remains open.
=== Steps to Reproduce ===
1. Download and build this project:
2. Place device in portrait mode
3. Swipe left-to-right to open ContextAction menu
4. Rotate device from portrait to landscape
=== Expected Behavior ===
ContextAction menu should remain open
=== Actual Behavior ===
ContextAction menu automatically closes

## Quick first glance from non-engineering team
This might be an implementation detail or bug in how _Xamarin.Forms_ implements the UI elements involved. It would be slightly more surprising (though perhaps still possible) that _Xamarin.iOS's_ binding layer over the native iOS context menu is causing the problem.
This does look to be a Xamarin.Forms issue. I loaded up the TableEditing sample for Xamarin.iOS and the contextaction stays visible while rotating, while I see the same behavior of it disappearing if I run the Interactivity sample in Forms.
I can confirm this is an XF issue. I saw it when I was fixing another bug last night.
