The commit are:

Emacs: 6f2036243f2 (2024-06-23, latest master)
Tree-sitter: 3da7deed (2024-06-08, version 0.22.6)

Also fails on old commits:
Emacs: ef01b634d21 (2024-01-18, emacs-29)
Tree-sitter: 870fb877 (2022-11-16, version 0.6.3)

But doesn't fail on:
Emacs: ce85d3811da (2024-06-18, recent emacs-29)
Tree-sitter: 3da7deed (2024-06-08, version 0.22.6)

Maybe it doesn't fail on recent emacs-29 because of the fix in 20af58d3a13?
But the same fix exists in latest master as well.
