Hi! I tested this PR on my Mac, MacOS latest and it works great.

It also helped me find another Pyrepl bug.

Hi. I think I found a bug with this PR. Tested on MacOS latest. I reproduced this in WezTerm and also Apple's Terminal.app.

In particular, if you type or paste a very long line into the terminal with this patch, leaving your cursor at the end, and then hit Ctrl/Cmd+/- a number of times to resize the text, you'll find the cursor in the middle of the line.

Thanks@feoh for catching that bug!
I made a mistake there. The previous method wasn't working well because reflow is terminal application behavior, making it difficult to guess rearranged content at this level. Now I just clear the screen and redraw everything to prevent any leftover characters.
I've tested this in Windows Terminal with WSL and it handles content exceeding window height well.
Does this fix it? Open to suggestions.

Some testcase might need to update if the behavior of resizing changes.

@ImFeH2 Hi! I'm delighted I could help!

Went to re-test and for some reason I can't check out this PR:

I'll try a fresh CPython checkout later from the hotel and see if that helps :)

Hi I'm very sorry to be the bearer of bad tidings but I'm seeing more issues with the fixed fix :\

Does this bug only appear in Wezterm so far? I tested it in Terminal.app on my MacOS VM and Windows Terminal - both display the text normally without this layout issue.
