Contents of chests are easily duplicated on realms compared to non realms session on Xbox when chest is moved by pistons

What I expected to happen was...:
Known duplication bug using chests and pistons ; tested on realms. On a non realms session timing is required to be almost perfect

What actually happened was...:
Super simple to duplicate; very lenient on timing (close to half a second) so the dup is much easier on realms than other.

Steps to Reproduce:
1. Have a chest on a sticky piston activated by button, pushing chest up.
2. open chest while extended, and hover over any item in chest.
3. just before signal retracts piston, move item.

4. Try on a console (I'm specifically using Xbox one) realms session and you will clearly tell how easier it is on realms versus the non realms session.
