Let's wait for a day at least.

BTW, you didn't answer one of my earlier questions namely this one:

In Bug#48129 Tom conjectures that this happens because some WMs do not
set _NET_WM_STATE.  Do you agree with him?  If so, wouldn't it make
sense to skip that x_get_current_wm_state check in MapNotify because it
fails on too many WMs?
