I tested this here, and just ensuring that _NET_WM_STATE exists did not
seem to make a difference. The proper solution, as I gather from reading
the mutter source, seems to be
 * Include _NET_WM_STATE_FOCUSED in _NET_SUPPORTED
 * For the active window, edit the list _NET_WM_STATE and include
_NET_WM_STATE_FOCUSED (just appending will keep enlarging the list)
 * For other windows, remove it from the list.

Greetings,
Joachim
