Fix bottom gap in card expansion panel

This commit fixes an unintended bottom gap in the card expansional
panel, observed in the Windows script collection's "Advanced settings".

This issue arrives from a `min-height` CSS property that no longer
aligns with the current method for achieving balanced padding. It's only
visible when an action (a card) contains too few scripts (nodes).
