Rotation popping when attaching the negatively scaled hand mesh of a motion controller the child of a box collision component (left hand)

The left hand in the VR template appears to pop as it rotates when assigning the mesh for the motion controller a parent that is a box collision component. This does not appear to affect the right hand. It only appears to affect the left hand that has been negatively scaled. If the negative scale is removed, the issue no longer occurs.

1. Make sure that oculus is hooked up and turned on
2. Download attached project
3. Open project
4. Play in VR Preview
5. Rotate your left hand in a waving motion (see video attached to users post on answer hub)
6. Notice that the rotation pops while rotating your left hand

Expected: The rotation for the left hand would be smooth (matching that of the right hand)
Result: The hand appears to pop as it rotates in a waving motion

[BUG?] Weird rotation issue with negative scale, possibly gimbal lock related
