I’m sure this is still an issue in 8.3, and has been for a long time in 8.1..
When trying to reorder items in a flex container, it’s awfully difficult. It’s mostly not as bad as in a column container (a big reason I stopped using them), but it’s a regular fight.
Nothing is better than a demo:
I’m trying to drag the WaterNSW title to be the 2nd to bottom item, but when I try, the items switch places back and forth and I end up now dragging the item below the one I was dragging… and the items didn’t swap places
One thing to note is that it’s rarely (if ever?) an issue when you move items UP, but pretty much always an issue moving them DOWN.
