So normally I know

Chunks can be loaded when other entities like items for example enters a nether portal

the issue

Items can't load chunks when entering a nether portal, while it can in java 

As you can see in the attached file I throw the item using dispenser and a command block always active with command "/say chunk loaded"

The command somehow doesn't run and the dispenser in the overworld won't continue to put out the item in it even after I throw another item from the nether
