Bug description

When using the "Toogle shaded state" keyboard shortcut on a window that is not shaded, it will shade, but then immediately loose the focus.

Unshading is then not possible anymore.

Even if one tries to manually focus the window (by clicking the title bar) it doesn't gain focus (one sees that it briefly gains it by the changed title bar colour, but then it immediately goes be to unfocused).

Clicking on the window’s entry in the panel’s window list, gives it the focus, but also unshades it (which I think may not be the best behaviour either?).

The same problem exists if one Alt-Tab (window-cycles) to a shaded window... it immediately unshades, which IMO also breaks quite some usefulness of the feature.

Steps to reproduce

Well as above.

Expected behavior

The window shouldn't loose the focus, and using the shortcut again, should unshade it.

And most likely, selecting a shaded window via the window list or via Alt-Tab shall not cause it to unshade.

Additional information

No response

Reproduce the issue on Debian sid using the shaded-state keyboard shortcut, then check the focus behavior when selecting a shaded window through the panel window list and Alt-Tab. Trace the relevant shading, focus, and window-cycling entry points; done means a shaded window keeps focus, can be unshaded with the shortcut, and stays shaded when selected through either method.
