Hitting Command(Ctrl) + S on in an RTC notebook results in a "File Changed" dialog

Same here. I have a docker container (based on python:bullseye) with only Jupyter Lab (v. 4.2.0) and the jupyter-collaboration extension.

Observations:

• You can either click "Revert" or "Overwrite", and it seems to work.
• It is nevertheless annoying.
• You may also close the editor, and rename it on the file browser, in which case it works as expected (no error dialog).
• You may click "Do not ask me again", in which case you are in the future forced to rename it via the file browser.

One workaround seems to be to add this snippet to /usr/local/share/jupyter/lab/settings/overrides.json (see https://jupyterlab.readthedocs.io/en/latest/user/directories.html#jupyterlab-user-settings-directory), which essentially does the same as "do not ask me again". Users will be forced to rename using the file browser, which at least might be less confusing than seeing an error everytime they want to rename a new document:

{
    "@jupyterlab/docmanager-extension:plugin": {
        "renameUntitledFileOnSave": false
    }
}

However, that is just an ad-hoc workaround. A cleaner solution would be nice :-)
