Description
Issue Reproduction
cmd.exe on tmux on WSL gets freezed.
I open a tmux session, where cmd.exe is running.
>wsl
$ tmux
$ cmd.exe
>
Ctrl+B D to detach
$ exit
Next, I reopen tmux.
>wsl
$ tmux a
>
I see the previous cmd.exe terminal.
But, any input to cmd.exe is ignored ( though input to tmux is valid for example Ctrl+B & to kill ) .
If this is a bug of tmux, then please let me know. I will post this issue on tmux repos.

Research direction
Start by reproducing the documented WSL, tmux, and cmd.exe sequence on the listed Windows, Ubuntu, and tmux versions. Check whether cmd.exe accepts input before detaching and after reattaching, while confirming tmux controls still work. Done means identifying the responsible layer or documenting a confirmed limitation with enough evidence for the next investigation.
