VRTK: Enabling/Disabling Interactables inside an Interactor's radius causing large framerate drop

Environment

*Source of VRTK (GitHub). *Version of VRTK (v4 Github master). *Version of the Unity software (Unity 2019.1.1f1). *Hardware used (Oculus). *SDK used (UnityXR).

Steps to reproduce

1. Take an Interactable.Primary_Grab.Secondary_Swap and drop it into the scene.
2. Shrink the Interactable to something small like 0.01, 0.01, 0.01 (small enough for 4 of them to fit inside an Interactor’s radius).
3. Duplicate the small Interactable 3 times, for 4 total.
4. Position the Interactor so it is encompassing all 4 Interactables.
5. Enable/Disable all 4 Interactables at once repeatedly, after a short time the framerate will drop severely.

NB: I’m guessing this happens even with just 1 Interactable, but it takes a lot more enables/disables to drop the framerate significantly.

Expected behavior

No frame drop.

Current behavior

Massive frame drop.
