Wrong colors in neovim terminal

[ngmoviedo]

The colors of neovim's built-in terminal do no match the expected prompt colors. May be a recurrence of #24. It's only happening in neovim (not in vim).

• Operating system/version: Arch Linux
• Terminal emulator/version: kitty 0.19.2
• Shell: fish, version 3.1.2
• echo $TERM: xterm-kitty

Further investigation is leading me to think that the error may be on neovim's side. I don't think it's kitty as I have recently tried it also in xterm, getting the same result. It looks similar to this neovim issue or this one

@ngmoviedo It is a neovim issue. It has already been fixed by neovim/neovim#10994

Please close this issue
