Should close #39428

The working directory of the `wsl.exe` program is set to a Linux path,
which is invalid on the Windows side, causing the terminal to crash. The
first spawn works because there is no active terminal view, allowing a
new shell (which checks for the remote) to be created. I cannot explain
why it works on SSH remote clients, but I may be missing something in
the remote connection implementation.

I don't have a Windows machine to test this, so I would appreciate
someone testing it. 🙏🏼

Release Notes:

- Fixed an issue where WSL terminals could not be splitted
