Remote SSH restarts repeatedly when opening remote git folder

[celynw]

Type: Bug

I am opening a folder on a remote computer (Ubuntu 22.04) using the Remote SSH extension. The folder I am opening is a git repository which has checked out a PR which is in the process of being reviewed. The already open tab is a python file with active comments.

After asking for my SSH passphrase, it loads and I can see my files and it opens the same files as I'm used to. The extensions start loading, I can see my git status (line colours, Source Control sidebar). My Python and Ruff extensions load.

Then this PR&I extension loads, and I can even see the inline comments in the open file. I can see on the status bar, it counts down "Files to analyze" which is from the Python extension, I believe (Pylance). When it gets to 1 (maybe after 1, and maybe this is unrelated) a few seconds later, the window reloads. At this point, if I don't have my SSH agent running, it will ask for my SSH passphrase again. After 3 attempts, it gives up on loading extensions, but I do still seem to have an SSH connection and can edit files.

Looking at the Output - Server:

I found this issue using the "Extension Bisect" feature of VSCode (awesome!). The problem is totally reproducible by me, and I have had this problem for at least a few days. I have had the extension for a good few months.
