Are you talking about the extra line-feed at the bottom of each section? If so, this bug is different. This bug increases the edit area by about 20px in height each time you click out, then back into the edit area. It seems to only affect this style of editor (mini editor) on Message Walls and Forums. As you can see, this blog comment is not affected.
