Fix for issue #111

Thanks for the PR. That was a silly oversight from my end.

The change looks good. The issue in CI seems to be unrelated. I will get this in soon as soon as I sort out the CI issue.

EDIT: Will fix it up in a follow up PR.

You're welcome.
I've just started to make use of tree-sitter and was very pleased to find this package - thanks.
