Observed behaviour

Passengers of an interaction entity with a default height tag are positioned as if height == 0, despite the default being 1.0 blocks.

How to reproduce

• Summon an interaction entity
• Summon another entity and use /ride to make it ride the interaction
• => It's not positioned ontop of the entity, but inside it.

(Even setting the height manually to 1.0 doesn't change anything, because the value doesn't change. You need to first change it to a different value and then back to 1.0 to achieve the expected result.)

Note: I just found out that the riding point also corrects itself when any NBT for the interaction entity is updated, such as the width.
