I encountered the same issue today. It seems like the autolayout properties aren’t immediately respected when the mode changes. If I manually change the size of the parent component, then the change seems to be noticed and it immediately readjusts itself. 

I have found this happens if the frame that doesn’t resize is a component instance and uses any kind of variable (no matter if it is color, spacing...)
