There is still annoying bug where users (probably people whose config is being converted from pre HG3 configs?) get empty edit summaries, just like Gurch had now: https://en.wikipedia.org/w/index.php?title=User:Gurch/huggle.yaml.js&oldid=887803938

This must not happen. I don't know how to tackle the source for this bug, but easiest workaround would probably be to disallow empty edit summaries and replace them with defaults.
