Workaround to make adaptive info use size override

currentWindowAdaptiveInfo() is not affected by using the ForcedSize
override, so the list detail scaffold directve will be calculated with
non-overridden values. This work around hoists the WindowAdaptiveInfo
so that we can pass in an appropriate value in tests.
