Mouse actions are not forwarded to git bash

[numEricL]

Windows Terminal version (or Windows build number)

1.9.1942.0

Other Software

Git bash, mintty 3.5.0 (x86_64-pc-msys) [Windows 18363]

Steps to reproduce

Add git bash to wt and launch (command line is "%PROGRAMFILES%\git\bin\bash.exe" --login -i -l)
Open vim and enable mouse vim -u NONE -c "set mouse=a"
Attempt to scroll

Expected Behavior

Vim to capture mouse inputs

Actual Behavior

Mouse inputs are handled by wt, e.g. scrolling affects the wt buffer.

Similar issues have been posted before, but these are before issue #376. I'm able to use wt with wsl and have mouse events forwarded as expected, so the problem seems specific to git bash. Git bash without wt however handles mouse events as expected.

Which version of vim are you running? I suspect that it is smarter than the average bear, but not quite smart enough yet; see #10321 (comment) for more info.

If vim is using VT sequences instead of Win32 APIs (which it should be doing owing to being hosted in Cygwin), scrolling should certainly work... but if it's falling back on the win32 APIs, it shouldn't support it even outside of Terminal. 🤔

Nice table! I don't think git bash has any cygwin dependencies and instead runs on top of mingw, is that incorrect?

I find that mouse input works as expected when running vim from cygwin inside and outside of wt.

cygwin ... mingw

Alas, the MSYS runtime is a fork of the Cygwin runtime! 😄

This is a really useful data point. Thank you!

@DHowett wait, does this mean this one is in fact a dupe, or not?

[DHowett]

I believe it is! Thanks!
