Re-write conditional checks for animation

When they were extracted into a separate method and split by type of
check, we lost some behavior that was guaranteed to be prevented by the
short-circuiting.

This CL makes sure that the checks do not depend on short circuiting by
removing side effect methods from the checks. If the checks pass (we can
animate) we do one last check that will try to enable fakeDrag.
