Hearthpwn

I was playing a game of hearthstone on my computer, testing out a quest shaman deck. At around turn 5, I happened to have my mouse over my Corrupt the Waters quest when I realized that some of my cards in my hand stuck out in front of the others when they weren't supposed to. I realized that the cards that were sticking out in front were all battlecry cards. I don't believe that this is an intended thing to happen when the quest is hovered over, although I could be wrong and Blizzard could just be doing this to help players keep track of what cards could be used to complete the quest. Can anyone else test this interaction?
