Fix Version/s: None
When summoning entities with a passenger entity then the root entities won't collide with other root entities, and the passengers won't collide with other passengers. Entities pass through one another.
I expected entities to push/collide with each other.
EDIT: Noticed it's still in previous versions like 1.10.2 and 1.9.4, might be related to
MC-15202 as in the fix for that one caused this.
EDIT2: Checked to make sure and the issue happens since 14w27a, it's not in the previous snapshot 14w26c, so that would actually point directly at changes done to fix
