Entities inside interactors can be interacted with if the player is also inside the interactor.

What I expected to happen was...:
I spawned an interactor (height:3f,width:3f) and wanted to use it to prevent players from opening a chest minecart inside. I expected the minecart to not be intractable through the interaction. I also expected the interaction to trigger when left/right clicking on the chest minecart.

What actually happened was...:
 The chest minecart could still be opened if I was also inside the interactor. The interaction did not trigger.

Steps to Reproduce:
1. Summon an interaction that is large enough to fit a player and an entity inside.
2. Summon an entity inside the interaction. Make sure it does not leave (By setting the NoAI nbt tag to 1b for example). 
3. Enter the interaction and try to interact with the entity. The interaction will not trigger and the entity will be interacted with.
