Open windows disappear after map change, bugging out all windows.

Describe the bug
If you have windows open (e.g. map list or map details) right before map change, they'll be hidden after map change and you can't open windows anymore, even after /reset

Expected behavior
Windows should reappear and you should be able to open new windows

To Reproduce
Example:

1. Go to an EvoSC server
2. Click on Details in the current map widget
3. Wait for map to change
4. Windows are gone and won't reappear
