Taking items from armorstand hand

Summary When I create armorstand mob with sword in hand and even try to add "Interactable: false" in options I still can take that item with second hand (if its empty)

Steps to reproduce After spawn armorstand mob and right click on him I can tahe his sword. Link to mob https://pastebin.com/7Fe1G8Q1

Current behavior Easy way to dupe items when mob have equip skill and possible way to get unwanted items on the server

Intended correct behavior The item should not be removable

Proposed fixes If I select option "Marker: true" then cant more take items from armorstand but then "gravity:true" no more works. Maybe there is a chance of block armorstand interactions with the other hand
