I am seeing this with code-server v4.0.2 -- which is the latest release available at this time (18 Feb 2022)
I do hope a new release is provided soon, as in 2 week the new semester begins and I would like to upgrade the version the students are using.

code-server: v4.0.2
VS Code: v1.63.0
Commit: 5cdfe74686aa73e023f8354a9a6014eb30caa7dd

@antofthy the fix for this is already in main. If you are using yarn/npm, you can use it today with yarn global add code-server@beta or you can use it when officially released in 4.0.3

Follow along here.
