The issues on gitworkshop have a header and a "Labels" field but what event tags do they use?
Apparently it's not "subject" nor "l"

It was a placeholder for labels added via NIP-32 so that they could be assigned by the author, maintainer(s) or potentially others after the issue has been created.
It shouldn't take much to add the feature but its never made it to the top of the todo pile. PRs welcome but hopefully I'll get to it soon.
