I’m now actually curious - what’s the bug in cmd.exe and why doesn’t that happen with other REPLs? I’m well aware that cmd.exe has its fair share of weird bugs, but on Windows it’s sometimes the only thing available. Plus, every third party terminal basically has to interface with the Windows GUI command-line program via screen-scraping, and so they inherit many of the same bugs. (The Windows Console architecture is fascinating - see https://devblogs.microsoft.com/commandline/windows-command-l... for a rundown!)
