      Distribution: ArchLinux

After alt-tabbing out of the running application then switching back to it the
application no longer receives keyboard inputs. Pressed key are appearing in
the terminal instead. Mouse keeps functioning properly. Seems to only affect
virtual desktop mode.

Reverting commit

(winex11: Ignore focus changes during WM_STATE transitions.)
fixes the problem for me.

Tested on XFCE 4.18 using XFWM window manager.
X.Org X Server 1.21.1.14.

Stranded 2 demo can be used to reproduce the problem. Start <Adventure> from
the main menu, use WASD to move around. After alt-tabbing keyboard no longer
works.
