Often phab will not clear out the “Comment” section on arc diffs. On a diff from just today, I made 10 or so inline comments, and then posted a “diff-level” comment at the bottom in the big text area, “I'm still reading, but here are some thoughts.”. That comment was posted, and shows up in the diff at the top now, great! The problem is that if I scroll back down, it still has my comment in the text box at the bottom :/ Also the phab homepage shows the yellow message icon indicating that i have unposted comments on the diff. This does not happen all the time, but definitely at least 1 or 2 times per week :/
