Jinx marking "shouldn" as misspelling in comment

[ashton314]

I'm working in elixir-mode, and Jinx is highlighting the chunk "shouldn" in "shouldn't" as misspelled. This doesn't happen emacs-lisp-mode or haskell-mode, so it's probably a problem in elixir-mode. I would love a pointer of where to look to see if I can fix this.

Here's an elpaca-test expression that highlights the error: (I dunno if you're using Elpaca or not. If you are, you should be able to drop the below code in a buffer and run eval-buffer, which should spin up a second Emacs session in a self-contained temporary location.)

;; -*- lexical-binding: t; -*-

(elpaca-test
  :interactive t
  :early-init
  (setq byte-compile-warnings '(not obsolete))
  (setq inhibit-startup-screen t)
  :init
  (load-theme 'modus-vivendi :no-confirm)
  (elpaca jinx)
  (elpaca elixir-mode)
  (elpaca-wait)

  (let ((buff (generate-new-buffer "Bug example")))
    (set-buffer buff)
    (elixir-mode)
    (jinx-mode)
    (insert "# this is an elixir comment that shouldn't have a spelling error here")
    (display-buffer buff))

  (use-package jinx
    :defer t
    :hook ((text-mode . jinx-mode)
           (prog-mode . jinx-mode))
    :bind (("C-;" . jinx-correct))
    :custom
    (jinx-camel-modes '(prog-mode))
    (jinx-delay 0.1)))

You can see in the elixir-mode buffer that the comment has a misspelling marked under shouldn in shouldn't. Any ideas where I could look to fix this?
