Component used: Fragment
Version used: 1.2.0-alpha01
Devices/Android versions reproduced on: API level 17 and below

androidx.transition needs setLayoutTransition for suppressing layouts during Fragment Transitions

FragmentContainerView was added in this CL. It disables setLayoutTransition.

However, androidx.transition uses setLayoutTransition to simulate the behavior of setSuppressLayout on API levels 17 and below.

RecyclerView had the same issue, and this CL fixed it.

Marked as fixed.

Thanks for the detailed analysis. This may not be an issue anymore since we've started using Main.immediate there but I' not sure; I'll try to create a test case.
