Level Bounds Calculated Incorrectly when using Particle System Components

If an Actor blueprint contains a particle system component (PSC), the Level bounds behave differently based on if the particle template is / is not Null.

If the template is Null, Level Bounds stretch from origin (0,0,0) to slightly around the actor (See PSCNotSet.png)

If the Template is set, Level Bounds reset position with the actor in the center (See PSCSet.png)

1. Open UE4 Editor (any project)
2. New Level -> Empty Level
3. Set Viewport view to Orthographic-Top
4. Add Level Bounds from Modes Tab
5. Create Blueprint based on Actor in Content Browser (ActorBP)
6. Open ActorBP and add ParticleSystemComponent
7. Add instance of ActorBP to viewport at (2000,-2000,0)
8. Select LevelBounds in World Outliner
   • Result of PSCNotSet.png
9. In ActorBP, Set PSC Template to TutorialParticleSystem
   • Template Dropdown
   • View Options
   • Show Engine Content
10. Compile and save blueprint
11. In editor viewport, change position of ActorBP instance to update Level Bounds
12. Select Level Bounds in World Outliner
    • Result of PSCSet.png

Result:
Having the particle system component causes the level bounds to calculate separate values than when the component is empty.

Expected:
Level Bounds are calculated the same regardless of if component is null.

Empty ParticleSystemComponent breaks bounds generated on owning actor
