TMUX killing all windows processes for an executable in all TMUX sessions when first TMUX WSL terminal is closed

[0xfMel]

Windows Version

Microsoft Windows [Version 10.0.22621.3155]

WSL Version

2.1.4.0

Are you using WSL 1 or WSL 2?

• WSL 2
• WSL 1

Kernel Version

5.15.146.1

Distro Version

Ubuntu 22.04

Other Software

TMUX 3.2a

Repro Steps

1. Open a wsl terminal
2. Run tmux to get inside a tmux session
3. Run a windows executable, tested issue happening with /mnt/c/Windows/System32/WindowsPowerShell/v1.0/powershell.exe
4. Open a second wsl terminal and do the same
5. close the first terminal
6. powershell exists on the second terminal too!

Expected Behavior

I would expect the executable to continue to run in the second terminal, as this is what happens with linux executables such as fish shell, and this is what happens when running outside of tmux.

Actual Behavior

powershell exits for every instance running inside of tmux created after the first.
you can close any other instance of tmux and it will work as expected, only when the first is closed do the rest exit too.
only happens when running the executable in tmux.
only happens for windows executables.
you can detach from the first tmux session and it will continue to run on the rest, but will still kill the rest when that terminal is closed.
tested happening with powershell terminal & alacritty.

I've been trying to find a work around but I could only get the other instances to stay alive if the first terminal is still alive, opening background tmux sessions which run the executable doesn't work.

It happens on WSL1 too, and it was supposed to have been fixed:
#709, #1007, #1511, #2252, #2391, #11157, #2138,#11237,#11112,#6242,#4690
All issues were marked as fixed by @therealkenc or @benhillis, but I just can't get it working.
