Ciao, 
this problem occurs with js-ts-mode when jsdoc is enabled. Occurs when you 
place the cursor in a comment highlighted by jsdoc.
This is the error message:

"treesit-show-paren-data--categorize: peculiar error: ("Cannot find the 
definition of the predicate in `treesit-thing-settings'" sexp-list)"

Could this be due to commit 493bb2eaf1610ec950e4a2f7229d6e1f939064b9 ?

GNU Emacs 31.0.50 (build 4, x86_64-pc-linux-gnu, GTK+ Version 3.24.43, cairo 
version 1.18.2) of 2025-01-09

Thanks.

Vincenzo

Recently I fixed bug#75198 and tested it on your mhtml-ts-mode
where it works nicely, and (treesit-language-at (point))
returns e.g. 'css' on embedded css.

However, now I discovered that (treesit-language-at (point))
returns 'javascript' on embedded jsdoc parts of a js file.

I wonder is this intended?

Since 'treesit-node-match-p' uses node's parser, I could use
(treesit-parser-language (treesit-node-parser (treesit-node-at (point))))
that returns 'jsdoc'.

But first I'd like to know why treesit-language-at doesn't return the same?
