Items lose their place holder entities when under invisibility potion

There is a floating item in armor stand's hand when armor stand has invisibility effect.

steps to perform:

Place a armor stand

Choose an item (idk why but it must be weapons, other items won't show up)

Equip armor stand with item

Effect armor stand by invisibility (by command or potions)

Walk around!

 

I also used this to mix items by placing different items in different armor stands  and throwing a potion of invisibility at them. To watch them clearly, place another armor stand.
