The pipeline uses tree-sitter provided by bookworm, which is v0.20.7, a pretty old version. And indeed, with that version of tree-sitter I can see the test failure.

I don't think this is practical.  I'd rather mark that test as
expected failure or "unstable", if we cannot know the version of the
tree-sitter library used for the test.

Or maybe you could rewrite the test so that it works in both old and
new versions of the library.

(FWIW, I use 0.20.8, with the latest grammar libraries, and the test
fails here as well.  Due to the issues with ABI breakage in the
tree-sitter library, I decided that I will upgrade only when 0.25 is
released, because it also bumps the language ABI version, which we can
detect in Emacs.)
