Comment 6 for bug 1875109

ah right I can see why that's not straightforward -- I was the reporter of the original bug on tmux and the reason I found the bug was due to a failing test case in the test suite of my text editor which uses tmux for integration tests

When I upgraded to 20.04 I noticed the same failures and reported this bug, and only after upgrading to the proposed version are those tests fixed

the original reproduction in the tmux bug was boiled down from a testcase in `resize_test.py`
