Visual Bug-Signs are no longer are held in the player's hand correctly

When playing on an ordinary survival world, I crafted some signs. Normally, these signs would be in my hand while having the slot active (Image 2 is from 1.7.9, the last version the signs are normal). As you can see by the first image, however, in the latest 1.8 snapshot as of June 25th, 2014, 14w26b, this visual is broken.
