We've decided to not animate it. The reason being performance. Because when it hides, it is also sizing the scrollable area above it, the animation can get choppy. We chose the option that was the fastest and didn't create a choppy effect. This is the same reasoning for the drop-downs not animating when opening. The animation of sizing the element and re-laying out the rest of the DOM had performance issues.
