Bug report
Bug description:
Pasting multiline content with long lines (more columns than the current terminal width) causes an unusual behavior on the REPL display, this happens on cmd and powershell.
Pasting this snippet in the REPL will cause this:
The interpreter actually handles the content correctly, but the editing of this is weird and leads to confusion.
