nerd-icons fail because treesit-auto makes (nil . glsl-ts-mode) entry in auto mode alist

[Schievel1]

Doom emacs uses nerd icons for it's mode-line.
When using treesit-auto it changes the auto-mode-alist so that one entry of it is (nil . glsl-ts-mode).
This causes problems when opening a file, because the function that searches for a fitting icon for that file in the modeline can not handle the nil it seems:

Without treesit-auto the entry in auto-mode-alist looks like this:
("\.glsl\'" . glsl-mode)

My treesit-auto config looks like this:

(use-package treesit-auto
:custom
  (treesit-auto-install 'prompt)
:config
  (treesit-auto-add-to-auto-mode-alist 'all)
  (global-treesit-auto-mode))

Doing a simple (delete 'glsl treesit-auto-langs) makes nerdicons work again. I don't know what glsl is so I don't care that much for it's ts mode. But something off in treesit-autos generating of auto-mode-alist it seems.
