@RichardBronosky (and @Arjentix and @zaid-g if you're still following),

Taken from https://vim.fandom.com/wiki/Change_cursor_shape_in_different_modes#For_Terminal_on_macOS adding this to my ~/.vim/vimrc gave me the same behavior in vim as in zsh.

None of these worked for me, but what finally got the cursor to reset was:

:silent !echo -ne "\e[2 q"

Did you come up with the name "zoomer" shell? That is hilarious
