Edit: This overlap-card situation rarely happen, so maybe the feature is not necessary because you can click to the card to shuffle and the overlap-card situation solved as Dakota said
This is an old feature. When I hover on a card, It will be brought to front and I can see its content if this card is covered by another card.
You can see the video for more.
