Box Collision component with physics interacts with the player capsule when set to Overlap only

Box Collision component with physics interacts with the player capsule when set to Overlap only. This only seems to happen when both the Box Collision and the player capsule are set to Generate Overlap Events.

This is a regression

1. Open the attached project
2. PIE
3. Press the E-key several times (10-20) quickly to spawn multiple box collisions

Results: Some of the box collision actors will slowly descend through the player capsule instead of ignoring collision and falling to the ground

Expected: For the box collision actor to completely ignore the player capsule except for overlaps

Physics simulated actor gets stuck in other actors it needs to overlap
