Classification:Other Bug Reproducible:Always
 
Summary:
On device rotation, keyboard extension’s view is not correctly resized.

Steps to Reproduce:
build and run the included project

Expected Results:
the keyboard’s view should resize on rotation.

Actual Results:
The keyboard’s view’s width remains unchanged.

Regression:
This is new between 8.1.3 and 8.3b2. Also new is that we’re now getting ‘willTransitionToTraitCollection:’ and ‘viewWIllTransitionToSize’ in UIInputVIewControllers (17472132) So it feels like these are probably related? 

Notes:
There’s a test project included that illustrates this issue.
