Support X11 forwarding from a remote Linux system using the Windows-native OpenSSH client

Is your feature request related to a problem:

Currently, it is possible to use X11 forwarding, but you have to use the SSH client inside WSL. However, I prefer using the Windows port of OpenSSH directly, so instead of calling wsl -- ssh -X <host>, I can just do ssh -X <host>. This currently does not seem to work.

Describe the solution you'd like:

1. I assume that the Windows port of OpenSSH would have to be adjusted so that it knows where to look for the local display server VM, so that it can set the correct $DISPLAY value. Alternatively, there should be a simple way to get the correct $DISPLAY value to configure manually before running ssh -X.

2. I don't understand the architecture of WSLg enough to know if there are any modifications necessary on the WSLg side.

Describe alternatives you've considered:

Using SSH from inside WSL, which works well.

Additional context:

No response

Start by tracing how the Windows-native OpenSSH client handles ssh -X and how WSLg exposes the local display server. Determine whether the required change belongs in the OpenSSH client, WSLg, or both; done means ssh -X <host> works from Windows without invoking WSL.
