Hi, 
this commit (bb1f97b643b77fc1f082d621bf533b4b14cf0c30) changed the definition 
of the JSX grammar to tree-sitter-javascript. This causes a node type error:
"
Error while displaying: (jit-lock-function 1) reported (treesit-query-error 
"Node type error at" 24 "(jsx_opening_element [(nested_identifier (identifier)) 
(identifier)] @font-lock-function-call-face) (jsx_closing_element 
[(nested_identifier (identifier)) (identifier)] @font- lock-function-call-face) 
(jsx_self_closing_element [(nested_identifier (identifier)) (identifier)] @font-
lock-function-call-face) (jsx_attribute (property_identifier) @font-lock-
constant-face)" "Debug the query with `treesit-query-validate'")
"
Indentation also has problems due to the deletion of "jsx_fragment" definition.

The patch in attachment fixes both problems.
Thank you
Vincenzo

p.s. nvim-treesitter tries to limit these problems by indicating which commit 
to install. Does it make sense to try a similar approach with emacs as well?
