Weird behaviour when font size up and down in WSL

[skyline75489]

Environment

Windows build number: [run `[Environment]::OSVersion` for powershell, or `ver` for cmd] 1909
Windows Terminal version (if applicable): From 0.10 to latest master

Any other software?

Steps to reproduce

I was playing around since we fixed #5479 recently. But I found that the content became weird and duplicate when I'm scaling font up & down.

Originaly there's only one prompt line. Scale the font to a very large one (I mean large enough to trigger line wraps) and down. Repeat.

Expected behavior

Well, anything less confusing would be good.

Actual behavior

After a couple of times, you got something like this:

I can only reproduce this in WSL. Distro does not seem to matter.

I'm not really concerned about the issue itself. I mean, it would appear very few people would actually do this in real life. What concerns me is the underlying issue that may affects other things. And I don't really get it why Powershell & cmd are exempt from this behaviour.

So I'm thinking this is definitely a /dupe of #5450, and I'm thinking honestly that both of these are related to #3088

This seems less like it's something we're doing, but more an artifact of how bash handles reprinting it's prompt. Compare gnome-terminal with conhost:

As soon as the prompt wraps onto a third line, you bash seems to handle unwrapping particularly poorly.
