@beat unless there are conflicts you dont need to update your branch. Everytime you push a commit it resets the count of testers

Thank you @brianteeman ! That was unexpected to me, as it's just a merge of the target that, if mergeable, doesn't get new tests. Additionally, github wasn't flagging it as automatically mergeable. Anyway, now I know (until I forget about it lol)!
