(Possible) bug
The "Late answers" and new "Low quality answers" queues have very similar (in fact, almost identical) UIs. In particular, the canned comments available when selecting "Delete" or "Recommend deletion" are the same.
If a second reviewer in one of those queues selects a comment that is already present, then a new comment isn't added; rather, the 'original' comment is automatically upvoted.
However, when the same comment is added from the 'other' queue, it is added a second time, as here (10k on SO required to see it, as it's already deleted). Should this also just upvote the existing comment?
Related: Do "Recommend deletion" votes from those two queues act cumulatively? That is, if (say) four such votes are required to kill the post, will one from "Late answers" and three from LQA finish the job?
