I think I ran into something similar some time ago. I did not report it because I had additional, perhaps other, problems. I test primarily on Linux and need to transfer data onto the windows machine on my left, which can be cumbersome hence why i don't use my windows machine that much.

Does it happen only on Windows Terminal, or also on Command Prompt?

Yes, both.
