Child component reports Parent during On Hit events instead of itself

This is a regression tested in //UE4/Release-4.27 cl18319896

Child collision component reports its' Parent during On Hit events instead of itself. 

1. Create or open any project
2. Create a Blueprint Actor
   1. Add a Capsule Collision component 
      1. Enable Simulate Physics
      2. Set Collision to 'Block All'
      3. Enable Simulation Generate Hit Events
      4. Create an On Component Hit event connected to a Print String Node
      5. Add a Format Text node in the format type "OnComponentHit - Capsule! Hitting: {Component}"
      6. Connect the Other Component out pin from the On Hit Event to the Format Text node
      7. Connect the Results to the Print String node
   2. Add a Box Collision component as a Child of the Capsule Component
      1. Set Scale to 2.0, 2.0, 2.0 so that it completely surrounds the Capsule
      2. Set Collision to 'Block All'
      3. Enable Simulation Generate Hit Events
      4. Create an On Component Hit event connected to a Print String Node
      5. Add a Format Text node in the format type "OnComponentHit - Box! Hitting: {Component}"
      6. Connect the Other Component out pin from the On Hit Event to the Format Text node
      7. Connect the Results to the Print String node
   3. Compile, Save, and close the Blueprint
3. Place the actor into the level above the floor
4. Play in Editor
5. Observe the Actor hitting the floor

Expected Results:
The Box Collision reports hitting the floor

Actual Results:
The Box Component hits the floor, but the Capsule Component reports instead.
