AppKit

Summary:

Clicking on a status bar item when the app is not currently active can get the keyWindow states into an inconsistent state:
1. window may receive `windowDidBecomeKey` despite not actually being the keyWindow
2. if the status bar item action foregrounds a different window, the previous key window will no longer receive key events (until the other window is closed).

--
Steps to Reproduce:
1. Open an app with active Window A that has a status bar item
2. Switch to another app
3. Click on the status bar item

Expected Results:
Window A should not receive `windowDidBecomeKey`

Actual Results:
Window A received `windowDidBecomeKey` while `isKeyWindow` is NO

---
Alternative steps to Reproduce:
Same as above, but if the status bar item handler call `makeKeyAndOrderFront` on a different Window B

Expected Results:
Window B should become the new key window, while Window A should be unaffected.

Actual Results:
Window B became new key window, but Window A will no longer receive key events even after the user activates Window A.
