Welded grandchildren do not overlap properly when their grandparent is simulating physics

Grandchildren (C in an attachment hierarchy of A < B < C) that are auto welded have issues related to overlap events when moving via physics. They tend to overlap later than they should. This does not affect their collision otherwise as can be seen in the provided example project.

1. Download the attached project
2. Press play
3. Watch the cubes, trigger, and print messages
   Result: The third cube overlaps well after it has already passed through the entire trigger, noting that it is not overlapping proerly
   Expected: All three cubes overlap properly
