issue_comments

the failure is #4283 and should be fixed by #4292. Also, there are warnings about *args, **kwargs, which will be fixed by the upcoming sphinx release (scheduled to be released in about 4 days). If we don't want to wait for that, I guess we can disable fail_on_warnings again?

Separately, I'm crunched at the moment but if anyone has any cycles to look at that failure that would be great. Doc build has not been kind to us recently...

That does look unrelated. Thanks @TomAugspurger

The doc failure looks unrelated:
