Vim keybindings are not working in contest mode. The bug appears to be that you exit insert mode as soon as you type text, but you aren't exactly in normal mode either - you just lose access to some Insert mode features and the cursor returns to normal mode appearance. Most keypresses still register, but you can't backspace correctly and delete a line. This backspacing issue basically breaks the vim mode completely - it's unusable. Is anyone else experiencing this? Found on both Safari Technology Preview and Chrome 100.
