Hi, this patch fix the treesit range rule for the jsdoc parser.
As you can see from the attached screenshots, with the previous rule the
parser throws an error (look at the modeline). With the new one, it doesn't
happen anymore, and now the font lock is correct (I applied both patches I
sent for this bug).
Thanks.
Vincenzo

Subject: [PATCH] Fix treesit range rule for jsdoc
The parser for jsdoc is local, so it is necessary for the range
rule to take this into account.
* lisp/progmodes/js.el (js-ts-mode): Add ':local' keyword.
* lisp/progmodes/js.el (js-ts-language-at-point): Removed
'js-ts-language-at-point'.
