When using a sub anim instance, the instance will continue to update/evaluate even when its value is not currently contributing to the final pose.

Steps to Reproduce

Open an animation BP and add a sub/linked anim instance to a blend by bool node.

In the sub instance's event graph, print on update or post evaluate events.

In the parent ABP, toggle the blend by bool value.


Expected: When the sub instance is switched off by the blend node, the sub instance should not update/evaluate.


Result: The sub instance always updates/evaluates.
