IPython copy bug while vi mode

[kalocsaibotond]

I launched IPython in vi mode, using the --TerminalInteractiveShell.editing_mode=vi flag, and copied large chunks of code (whole file) for testing a bug, when I pasted the code. When the pasting occurs, a is cut out from the pasted string and then placed at the end of the pasted string. The choice of the character is seemingly random, but it ruins the code more often. This happens for whole file copy. If copy a segment of the file then only the character appears. It is very confusing.

I was using:

• Windows 10
• IPython 8.20.0
• Python 3.11.7
• WezTerm 20240203-110809-5046fc22
• I copied from Neovim 0.9.5 into IPython console on a pane.
