1. Open any ST 2.x app (haven't tested with ST 1) on an Android 4(.0.3) device, e.g. the kitchensink:

Update: This issue is easy reproducable on Android 2 as well, see post #7 (http://www.sencha.com/forum/showthre...l=1#post883318)

2. Tap on the url in the address bar to select it and trigger the display of the keyboard. The keyboard will stay being displayed since the url is selected.

3. Hit the reload button

4. After the reload is done (make sure the keyboard is still shown) tap somewhere within the app to dismiss the keyboard

Actual Result:
The viewport isn't expanded to its full height, only ~half of the app is visible. Space of keyboard is kept blank.
This also happens for apps with viewport: autoMaximize: true.
I can reproduce this from ST 2.0 till 2.1 beta 2.
