Whisker menu unminimizes windows

When I click on whisker menu, my windows get unminimized.

This happens only when I minimize windows using the “show desktop” icon on xfce4-panel.

If I individually minimize each window, everything works fine.

Is this a bug or a misconfiguration?

Couldn’t reproduce on my side. Xubuntu 20.10. Just fyi.

I was using Kwin as my compositor/window manager.
After reverting to xfwm, the issue disappeared.
So, I guess it has something to do with the Xfce+Kwin mix.
