Current Behavior

when I mistype a word on the end of a line and proceed to the next line before I catch it, then backspace to the previous line where the error occurred, it locks the cursor on that line for a time and you can't proceeded with the test. I'm not sure whether it locks for a time duration or if mashing the keyboard enough unlocks it, but after a time you can get the cursor unlocked. just wanted to put this here incase it helps, as I don't really want to do a lot of testing for this. feel free to close if you just don't want to deal with it. Thanks for building such a wonderful platform!

Anything else?

No response

No files, tests, or entry points are identified. First reproduce the described sequence in the typing test: correct an end-of-line error only after advancing, then backspace to that line; trace the cursor and input handling involved. Done means the cursor continues normally after returning to the previous line, with the behavior verified in the affected scenario.
