Yes That's The Problem It's Already In The Title, This Makes Some Redstone Users, Commands Block And PvP Server Owners Feel Disappointed...

Because some servers and realms definitely have something called a kit, which is usually after they do something, the refilled chest will remain open to make it easier for many people, But After Seeing Catalog Update 1.21.0 : "Containers being cloned over no longer keep their container screens open and cause crashes",I Feel A Bit Disappointed Because Now The Gacha System Using Chests Now Doesn't Look Good Anymore, Because Now We Can't See The Chest Animation Anymore Because Of The Container Directly Closed...

Conclusion, Please Bring Back This Feature Or Make A DataPack For Minecraft Bedrock So You Can See Clones With Open Containers...
