We FragmentContainerView was created, https://android-review.googlesource.com/c/platform/frameworks/support/+/985243/ ensured that unlike FragmentLayout that consumed all of the insets when using fitSystemWindows=true, FragmentContainerView would always dispatch the insets to child views, regardless of the value.

Now for FragmentContainerView fitSystemWindows=true is a no-op, but we should instead throw an error and indicate to the user that if they would like to handle insets they should do so at each individual fragment view.
