xwm: reject requests for WM_STATE_ICONIC
Created by: junglerobba
Fix for https://github.com/swaywm/sway/issues/4324 Fix for this issue in i3: https://github.com/i3/i3/pull/3421
For compatibility reasons, wine sets the iconic state without waiting for the window manager, so if it is unsupported, there is no way to recover the window from that state. This simply sets the state back to normal immediately to work around that problem.
