Animate status bar max-height and margin-top 

When collapsed, the max-height is set to 0px. When expanded, max-height is set to 50px, margin-top is set to 0px. When expanded and when the timeline is not scrolled down to the bottom, margin-top is set to -50px to offset the change in height, keeping it at the same scroll position.

Without the animation, there would be a jump when the user starts scrolling up from the bottom whilst the StatusBar is expanded.
