Unable to persist temporary documents on Linux

[nc7s]

Describe the bug
When exiting, temporary documents (Untitled-x) trigger a prompt: "Do you want to save the changes you made to (...)? Your changes will be lost if you don't save them." It does when "Don't Save" is chosen.

Please confirm that this problem is VSCodium-specific

• This bug doesn't happen if I use Microsoft's Visual Studio Code. It only happens in VSCodium.

Please confirm that the issue/resolution isn't already documented

• I checked the Docs page and the Troubleshooting page and my issue is not mentioned there.

To Reproduce
Steps to reproduce the behavior:

1. Ctrl-N to open a new temporary document
2. Write something
3. Close the application to see the prompt
4. Click "Don't save" and reopen to see it's indeed lost

Expected behavior
The temporary document should have persisted, as on Windows and in original VS Code.

Have you tested Visual Studio Code on linux in a podman container?

Yes, just created a toolbox container and installed VS Code official rpm in it, ran with the same command. It persisted the document.
