-Description:
-assertCSSResponsive() and assertSVGResponsive() take a property
-specific interpolation and a list of style configurations with interpolation
-expectations that apply to each configuration.
-It starts the interpolation in every configuration, changes the
-state to every other configuration (n * (n - 1) complexity) and asserts that
-each destination configuration's expectations are met.
-Each animation target can be assigned custom styles via the ".target" selector.
-This test is designed to catch stale interpolation caches.
-Set from/to to the exported neutralKeyframe object to use neutral keyframes.
