Dear Mojang

Issue:

There has been a major duping problem in many minecraft realms. How this duping works is as shown in the attachment below.  The reason why this game-breaking dupe is such a problem is because this glitch is very well-known and simple to design. All you have to do is to arrange the items as shown in the picture and take your items from the chest at a very precise moment. Furthermore, this glitch is very well known that realm admins have to stalk players if they are duping in their realm.

Important Notes

I think that this glitch has been reported and resolved a long time ago. However, people are still able to use this glitch in the latest version of minecraft.

It is far more difficult to use this glitch in single player compared to realms. For instance, I am able to replicate this glitch in 1.11.04 (to duplicate items) but the timing is very very precise. In comparison, in bedrock 1.9 (Realm multiplayer), the timing required for this glitch is more lenient.

I suggest this issue to be addressed immediately as it affects minecraft Realms significantly. Thank you for your time.

Regards
