Because this exploit has been widely known for years and has not been fixed by Mojang, we decided that it was worth allowing people to toggle it on/off due to how easy it is to make it configurable. It should be noted that this decision does not promise all future exploits will be configurable.

Subject: [PATCH] Do not run close logic for inventories on chunk unload
|
|
|
|
Still call the event and change the active container though. We
|
|
want to avoid close logic because it's possible to load the
|
|
chunk through it. This should also be OK from a leak prevention/
|
|
state desync POV because the TE is getting unloaded anyways.
