Hmm, I think it should be "WHATWG GitHub Labels" (or maybe just "GitHub Labels"; the prefixing with WHATWG is rather arbitrary), given that it's also "Code of Conduct" on https://whatwg.org/code-of-conduct.

I thought "Headers are sentence cased" @annevk? Methinks you are inferring single # is the "Title" and ##... are "Headers". Am I correct? Nonetheless, I concur about WHATWG prefix.

Removed in 81a410d as per your request.

Yeah, sorry for being vague. A single # is the "title" (that matches the style on whatwg.org anyway).

[snuggs]

@annevk copy that!

Fixed in 3e6f355

Also took the liberty to rebase atop our most recent patches in master.

We should be good to go on this one. Much more to do 😎

Thanks!
