Bug 499109

SUMMARY
When I switch activities with hotkey and the active desktop of the activities differ, clicking on a window will result in the focus being on the original activity. Typing will type to the program on the original activity, hovering around will show tooltips from the program on the original activity, etc. The focus can be brought back by clicking on the panel or showing-unshowing he desktop.


STEPS TO REPRODUCE
1. Create to activities (A1 and A2) with two desktops (D1 and D2) on each. Assign hotkeys to the activities 
2. Start a program on A1-D1 and start another at A2-D2
3. Work with program at A2-D2. 
4. Switch to A1 with an assigned hotkey. This will land you at A1-D1, since D1 was the active desktop on A1.
5. Click on the window there. 

OBSERVED RESULT
The window and program on A1-D1 loses focus and e.g. if you type, it will be typed in the program at A2-D2

EXPECTED RESULT
The focus should not go back to A2-D2

ADDITIONAL INFORMATION
This breaks the use of activities and can potentially results in data loss if unintended key-presses go to programs on other activity.
