Verification builds:

ver. 1.11.4, Win10

Summary:

If someone is sitting on an entity, the component "minecraft:spawn_entity" is no longer executed.

Impact:

We are unable to publish a piece of content as we had no success in finding an alternative to this mechanic

Repro Steps:

1. Create a custom entity with a seat and a looping spawn_entity component (The bug exists, no matter if the spawn_entity component is looped or only executed once. For test purposes we recommend to loop the component.)
2. Summon the previously created entity
3. notice the entity spawning an entity
4. ride the entity and notice the behaviors stop working

Observed Results:

The entity with the spawn_entity component stops spawning other entities when being ridden

Expected Results:

The spawn_entity component should not be affected by whether the entity is ridden or not.

Regression Builds:

We have no comparison to previous versions.
