[MCPE-159116] An item's "transform_item" event no longer works

The transform_item event for items no longer works.

Example:

    "events": {
        "use_item":{
            "sequence": [
                {
                    "transform_item": {
                        "transform": "minecraft:apple"
                    },
                    "run_command": {
                        "command": [
                            "say I'm an apple!"
                        ],
                        "target": "holder"
                    }
                }
            ]
        }
     }

Expected result is that when the item's 'use_item' event is triggered, that the item transforms into an apple and the player says "I'm an apple!".

Actual result is that the item does not transform and the player says "I'm an apple!".

This worked previous to version 1.19.10.
