The number of items in the chest are still shown even when hovering over a skulker box

What I expected to happen was...:
the number next to the item to be hidden 

What actually happened was...:
It covered part of the shulker box gui

Steps to Reproduce:
1. place a chest and put a items dotted around inside it 
2. place a shulkerbox with random items in it in one of the earlier slots
3. the item counter should be shown through the shulkers gui
