`spell-fu` is not working as expected in *most* programming comments

What happened?

spell-fu is working to check the spelling in comments as expected on my system, but only in elsip-mode: is not working in any other prog-mode derivative on my system that I’ve checked.

What did you expect to happen?

I expected spell-fu to underline mispelled words in comments, and to find spelling errors when I run spell-fu-buffer.

Steps to reproduce

  1. I have (spell +everywhere) configured.
  2. I ensure spell-fu is running in the modes (e.g., python or ocaml) via SPC h m (and also that flyspell is not running).
  3. Type some nonsense string in a comment in a buffer reading some Python or OCaml, and observe no overlay for the error, and no errors detected whenn running spull-fu-buffer.
  4. But spelling in comments is checked in .el files running elsip-mode.

Thanks in advance for any tips on how to debug here! I’ve tried looking at the doom config for the :checker spell setting, comparing spell-fu variables, running thru relevant advice in How to debug issues, updating, running doctor, etc. I’m not sure what else to do here to figure out what’s going wrong! :pray:
