Thanks!

Thanks @hukkin for the merge! Any plan for a new release of mdformat-gfm?

I'll make a release when the failing test is fixed. Can't promise when. At a quick glance it seems to me like it's a result of an updated markdown-it-py or maybe linkify-it-py . If markdown-it-py, it would be interesting to know how Javascript markdown-it works here and whether the change is a bug or intended new behavior.

FWIW, #30 should resolve the CI failures and works on my fork: https://github.com/KyleKing/mdformat-gfm/actions/runs/7477630457. I added a few notes on what is happening there
