bug#39072: 26.3; Pressing C-z in fullscreen messes all frames

I do have several layers of weird to my windows setup. If this isn't easy for others to reproduce it's most likely PEBAC. More, seems a good probability this is something I've done to Windows rather than something I've done to Emacs. We can close this if no one else reports in.

It will take some time to peel them my customizations. I can I update the closed ticket if I have new information at that point? My assumption is that I won't then be able to reproduce and will only have what in my windows setup caused this to share, so looking for the right place to put that if it seems useful.

I have a Windows 10 box, and I can't reproduce it either.
