This question: open pop up window on map marker from outside map canvas after click an anchor tag in drupal 7 using gmap, location was pretty bad when I downvoted it. A bit more than a single line. It was edited later. Apparently edit happened inside the grace period. So now there is not-that-bad question I would probably leave alone, without downvote. But I can't un-downvote it, due to lack of entry in question's revision history.
I think un-downvote should be possible even if edit happened inside grace period. Do you share that view?
