Add Particle System Component Template Context not functioning

Also Reproduced in Main Promotable-CL-2535351

In the Add Particle System Component node, there is a Component Template Context input which does not seem to function and establish a template for the added particle Component.

Following is the Blueprint setup for the issue and the workaround:

[Image Removed]

1. Open QAGame Editor
2. Create a New Actor Blueprint
3. In the New Blueprint's Viewport, Add ParticleSystem'/Game/QA_Assets/Particles/Systems/Additive_Test.Additive_Test' (or any Particle System) as a Particle Component
4. Uncheck Auto-Activate in the added Particle Component
5. In the Event Graph, Set up a system as shown in the attached picture.

RESULTS: "K" Press does not spawn particle system.

EXPECTED: "K" Press does spawn particle system.
