Bad frame on orientation change

[ivanornes]

Hi!

I just found out that when modifying the test app for handling multiple orientations the framework doesn't work quite well. The size of the transition container view is different from the main view.

The steps to reproduce the issue are:

• Swiping up the LineView
• Swiping down
• Changing the orientation
• Swiping up again

Is there any quick way to fix it?
Thanks!
