Short-duration animation of constraints on groups with tile layouts have popping artifacts

Steps to reproduce:
1. Build and run the attached app
2. Click the "State 1/2 Slow" button a couple times
3. Click the "State 1/2" button a couple times and compare animations

Actual Results:
Animation played when clicking the non-slow button has a popping artifact. The animation that pops has a duration less than the duration of the animations on the tile-layout group's children. The animation that doesn't pop has a duration equal to that of the animations on the group's children.

Expected Results:
No popping artifacts on the animation regardless of duration.

Workaround (if any):
