To this day I still attempt never to click inside a running cmd / powershell console. Too many times script execution has been halted by this. It is probably something that has been fixed long time ago but I am still a bit paranoid about it.
It isn't a bug, you could actually toggle this behavior. Don't know how the option was called and cannot find it in Windows 11. But it certainly was still there in the latest Win10 build.
I think it was called something like quick edit or similar.
