User-Agent:       Mozilla/5.0 (Windows NT 5.1; rv:2.0) Gecko/20100101 Firefox/4.0

If Firefox isn't focused and you try to focus it by clicking on the resize grip in the lower-right corner of the window, resizing mode will get stuck on as if you were holding down the mouse button.  You have to click again to get out of resize mode.

The same does not happen for textarea resize grips.

Reproducible: Always

Steps to Reproduce:
1. Focus some window other than Firefox.
2. Click (and release) on the resize grip.
3. Move the mouse.
Actual Results:  
Window resizing will track the mouse movements.  To restore normal operation, click and release the mouse button again.

Expected Results:  
Firefox should get focus, but the window should not resize, since no drag operation was done.

Default theme.
