@initiator not working when experimental function "upcoming creator feature" is enabled

when experimental function: "upcoming creator feature" is active, @initiator does not work on npcs.

when you try to use @initiator on npcs with the "upcoming creator feature" active, the npc closes its conversation, as if the @initiator was not recognized by the npc.

I don't use or used addons or texture packs, this error was found when I tried to use it in a realms with this function active, decided to test it in a world without being realms, and the @initiator still didn't work. I went after finding out why, and doing some tests, I discovered that the "upcoming creator feature" makes @initiator not work.

step to reproduce:

1. Activate the experimental "upcoming creator feature".

2. Use @initiator on npc. (example: /give @initiator diamond 1 0)

Observed Results:
@initiator when the "upcoming creator feature" is active does not work.

Expected Results:

@initiator should still work even if the "upcoming creator feature" is active.
