Comments are broken in qmd files

[dshemnv]

I noticed that when I try to comment lines inside a qmd file, it behaves strangely and mixes up python and markdown comment strings. This also affects regular md files.

Here is an example

Screencast_20251205_142419.webm

I use the default Neovim keybinding gcc.

Disabling quarto-nvim solves the issue in md files.

Novim version: v0.11.5
quarto: v1.8.26

Commenting everything in quarto.lua solves the issue for md files.
