[xmonad] Is there a way to reparent a window manually?

I've attached the simplest config that still reproduces the problem (actually, the problem can be reproduced even with using `def` instead of `xfceConfig`, but then the system breaks in a vindictive ways). Also I'm attaching a screenshot that showcases the problem - see several "menus" being visible simultaneously.

Maybe my problem is due to xmonad-xfce interactions? What DE are you running (if any)?

Checked - I do have `ewmh` configured since I use `xfceConfig` (which builds upon `desktopConfig` which in turn applies `ewmh`).

I'm not sure how to test this. Moreover, why _NET_WORKAREA should be related to sub-window repainting?

Best regards,
