Hi, 
I'm trying to figure out how to properly use treesit-range-rules for my
php-ts-mode (you can find it here https://github.com/vpxyz/php-ts-mode, there 
are still several things to fix.).
Currently the rules I am using are as follows:
(setq-local treesit-range-settings
	    (treesit-range-rules
	     :embed 'html
	     :host 'php
	     ;;:local t
	     '((program (text) @cap)
	       (text_interpolation (text) @cap))

	     :embed 'javascript
	     :host 'html
	     ;;:local t
	     '((script_element
		(start_tag (tag_name))
		(raw_text) @cap))

	     :embed 'css
	     :host 'html
	     ;;:local t
	     '((style_element
		(start_tag (tag_name))
		(raw_text) @cap))))

I also tried different combinations, even with the new :local flag. However, I 
couldn't find a way to prevent built-in language parsers from modifying 
highlighted syntax outside of the ranges captured by queries.
I used php-mode as a comparison. For example you can see how it behaves with 
the two files https://github.com/emacs-php/php-mode/blob/master/tests/8.0/
attribute/class.php or https://github.com/emacs-php/php-mode/blob/master/ 
tests/issue-66-namespace.php.
It is possible to set a php-ts-mode-disable-inject variable to enable or 
disable the parsers for html/css/javascript to see the differences.

What am I doing wrong?
Thank you

Vincenzo
