Hello and thanks for the additional information. I tried to reproduce the issue but with no success. I could observe the "window size dance" you described by doing a detach/resize/resize- back/attach, but I can't tell if it could be related to tmux dropping out from copy mode.
An interesting data point could be checking if tmux from Groovy or Hirsute also show the problem. If it does not that it means that it has been fixed (likely upstream) between those releases, and we can start looking at the commit history or bisecting to find out what fixed it. You could also try to compile tmux from source and see if the latest version from git [1] also has the problem. If it does, what I suggest is to file an upstream bug. Personally I'd go this route. If you do file an upstream bug please link it to this bug report. Thanks!
