Can you explain why an after-change hook is at all needed?  Why not
pass to tree-sitter the chunk that jit-lock is going to fontify?
AFAIU, tree-sitter is well suited for parsing incomplete source
chunks.  OTOH, using an after-change hook has its downsides, even if
disregard slow-down (which I wouldn't).
