Thank you Yuan! 

It works better, but the range update seems to be delayed or not triggered by e.g. yank or undo, as you can see in the attached screencast.
After the yank the ranges are:
((#<treesit-parser for html> ((2 . 483))) (#<treesit-parser for css> ((1 . 1))) (#<treesit-parser for javascript> ((1 . 1))) (#<treesit-parser for php> nil) (#<treesit-parser for phpdoc> ((377 . 435))))
