Avoid the cell background showing past the left/top of the border of the cell, by using left/top-aligned characters (▛▌▀) rather than centered border characters (┼┆┄).
I was hoping this would fix the Python rocket icon showing in the dock on macOS, but it doesn't. It still stays until the program exits.
Might still be good to do though.
