Card stacking boxes have confusing display

[AdamH]

I've attached an image of what it looks like when my opponent has five cards in their hand.

If I'm looking at this display, what it looks like to me is that they have a stack of five cards, then four other cards on top of that. The red number box means that there is a stack of cards here and there shouldn't be splayed cards that go with that stack. Every time I look at this part of the UI I'm confused as to how my opponent got 9 cards in hand and have to think through it again.

Either splay the cards, or if there are too many, show one card and the red number box. Doing both just doesn't make sense.
