This looks like a WM bug, we request a minimization and the WM does not minimize the window but instead updates WM_STATE with NormalState. There is no way for us to know that this is not a user action, and we cannot ignore it or override it safely.
We could, perhaps, decide that if the window has an unmap pending we should prefer it over user actions, but I'm not sure it is a good idea to add such logic and it feels brittle.
