I'm not sure if its already been addressed, but I noticed a day or two ago that when I added color to text like so that the color tab would not go away. This was after editing ta post, leaving the palate hovering where it was during editing. Clicking edit didn't change this and the palate wasn't responsive, leading me to open another one on top of the bugged one with mixed results.
Reloading the page fixed this, but the issue...testing.
Update: yes, the issue is still there and occurs when saving edits without closing the palate, first.
