Hi,
Thank you for your fix! I just compiled the latest Emacs-30 code and tested several files that had problems before. It’s working very well so far.

I fixed the bug I discovered; and guess what, that totally fixed this bug! So this bug isn’t caused by the tree-sitter bug, despite having similar symptoms.  

When the next pretest comes out, please give it a try and see if you can still see the bug. Or you can clone the emacs-30 branch and check it out now.  

Thanks again for the report! Would’ve been really bad if we didn’t discover this bug before releasing Emacs 30.
