I decided to put the new icon system to the test by putting 64 different items into a single bundle. After this I attempted to empty. Obviously because there aren't 64 slots in the inventory not everything could fit. However, instead of either dropping the remaining items on the ground or keeping them stored until the inventory is emptied, the items will just disappear.

Did you try in creative or survival mode? AFAIK the items get dropped on the ground in survival.
