/**
 Tests that validate collapsing and expanding MDCFloatingButton does not change
 pointerInteractionEnabled. This behavior is being tested because MDCFloatingButton temporarily sets
 pointerInteractionEnabled to NO when changing between collapsed and expanded states to address an
 issue where the iPad pointer would remain floating-button-shaped after the button it was hovering
 over collapsed.
