Yeah, and that's what I was experiencing earlier as well.  IIRC the
version I used was a compile from master, and was tagged with 20.7.  So
my 2 cents would be either a bug in treesitter upstream, or some new api
that we don't support yet.  I didn't do too much digging at the time
because I had several other patches in the loop and wanted to continue
working on those:)

Hope this helps,
Theo
