Armor on armorstands can dissappear

If you put a piece of armor (works with best with chestplates) on an armorstand, look at it and then double click with the right and left mouse button at the same time, the armor disappears. In 1.15 snapshots it´s also possible to create a fake item if you do the same without putting the armor on first. Only works in survival mode.

Edit: Fake item doesn´t work anymore.
