Stacks not working in Preview mode
I'm not sure if this is a limitation of stacks, but they don't seem to be responsive in preview mode.
In Design, I have come 'card' components which have been grouped into a Stack. The components have a default state (expanded), and also a minimised (collapsed) state. Toggling between the two states in Design mode works fine.


But in preview mode, they aren't responsive.

Any ideas on how to fix this?
