Summary:
When you break an armor stand in creative, any items that were on the stand drop to the ground. This isn't consistent with the Java edition, nor is it consistent with item drops in creative generally.

Steps to Reproduce: (creative mode)

1. Place an armour stand
2. Equip it with armour
3. Break the armour stand

Observed Results:
The armour stand disappears, and any items it had on, drop to the ground.

Expected Results:
It should not drop anything in creative, only in survival. (Java Parity)

Screenshots/Videos attached: Yes

Notes:
Compare this to item frames; another entity that holds items. When it is punched in creative, it doesn't drop the item it held.
