The combobulate-mode variable is nil even when combobulate works fine

[DamienCassou]

1. Execute

   $ emacs -Q \
       --eval "(setq treesit-extra-load-path '(\"/...path-to-grammars.../\"))" \
       --eval "(add-to-list 'load-path \"~/.emacs.d/lib/combobulate\")" \
       --eval "(require 'combobulate)"

2. In the *scratch* buffer, type M-x js-ts-mode
3. Type M-x combobulate-mode

Expected: The variable combobulate-mode to have value t

Actual: The variable has value nil.

Note:

• Combulate works fine. I just find weird that this variable has value nil even though its documentation suggests it should be non-nil.
• combobulate-javascript-minor-mode is t

Given that combobulate-mode is not a minor-mode, do we need this variable?

Yes, I should probably commit to using it or scratch it.
