Incorrect sizing after orientation change
Sencha Touch version tested:
- only default ext-all.css
Platform tested against:
- iOS 5 (works fine)
- Android 2.x (not sure the version of the phone, but it worked fine)
- Android 4.0.4
- Android 4.1.1
- When rotating the device from landscape to portrait, while an overlay is present, the resulting layout will make everything look smaller.
- What is happening is, say that in landscape orientation the width and height of the browser is 1024x496(this is from the Galaxy Tab). Then after rotation, the width doesn't update correctly. The width remains 1024, and the height scales accordingly with the correct aspect ration of the device. So in this case the width and height are now 1024x1488. So the content is drawn for a screen size larger than what it was previously, resulting in everything looking smaller.

Steps to reproduce the problem:
This MUST be done on a mobile device. I have not been able to reproduce it in Chrome on a desktop. (tried resizing the window, doesn't have the same behavior)
- hold your device in a landscape orientation.
- press one of the "show" buttons
- rotate the device 90 degrees
The result that was expected:
- Items on the screen should appear to the same scale as they were before the orientation change
- everything looks tiny

Debugging already done:
I have checked the values of some variables before and after changing the orientation of the device. The values I am showing here are from a Samsung Galaxy Tab.
