Comment 2 for bug 1532862

OK, I've reproduced this. Adding my notes here:

* After alt+tab, focus is successfully put back to the app. It works with touch apps.
* In the case of gedit, the focus *is* being put back to gedit, however, inside the XMir container the focus gets messed up.
* after alt+tab back to gedit, the arrow keys are still functional, pressing left/right/down/up will navigate to the menu

=> This makes me think that pressing the alt key, for the alt+tab, will also cause the xmir app to act on it and with that focus the menu bar.

Following that, a single alt press inside the app should unfocus the menu bar and allow typing in gedit again. Testing that on my N7 with BT keyboard confirms this.

Now I'm not 100% sure yet if this is an issue in unity or the xmir container. Will try to figure what the correct behaviour should be.
