How to reproduce:
- Start Awesome WM with my current configuration. There should now be an XTerm window in the first tag ("shell") and a Firefox window in the second tag ("browser").
- Move the mouse pointer to the middle of the left half of the screen.
- Toggle the second tag with Ctrl-Mod4-2.
Now the mouse pointer should be on top of the Firefox window, but the XTerm window is still focused. Hence the question: How do I ensure that Awesome WM updates focus when toggling tags?
