New chest bugs

When you hold a chest in creative, it is a flat item rather than a 3D block model like the other blocks. Also, when you tap on both a single chest and a doule chest, the opening animation runs as if you opened the chest for the minimum amount of time.

Picture links (for now until i upload them properly):
