Broken since introduction of add-entity

Summary:

When creating a custom entity that the player can ride the entity's health is not displayed while it is being ridden like you get with horses. I suspect that this is maybe hard coded to vanilla entities only.

• The custom entity contained the following components:
• interact
• type_family
• collision_box
• damage_sensor
• movement
• movement.basic
• navigation.walk
• jump.static
• push_through
• fire_immune
• input_ground_controlled
• physics
• inventory
• equippable
• timer
• fall_damage
• environment_sensor
• health

If I change the identifier in the custom entity's description from it's custom identifier to minecraft:horse I am able to see it's health from the heath component.

Affects upcoming content

Repro Steps:

• Create a custom entity and make it rideable
• Apply the BP to a world and join it
• Spawn the entity, mount it and observe the result
• Close the world and change the identifier to minecraft:horse
• Observe the expected result

Observed Results:

The entity's health is not displayed above the player's hotbar

Expected Results:

The entity's health displays correctly while riding it
