That issue should have been taken care of in 2.12. What happens when you attempt to make a single row? Are you seeing icons go off to the side in the area that is not visible?
Well, i don't think it was solved, at least for what I can see ....
Single rows behave as expected, I'm talking about single columns, I cannot make a fence with less than 2 columns. If I try to resize it to make a single column, the icons don't re-arrange themselves, they simply stay where they are and I'm hiding them as I move the edge of the fence. See attached
