Browsing their Docs has this weird, glitchy animation. Where is it coming from?

Another small bug, the ::selection colour in CSS matches the yellow background on your homepage so if you select text there (in the 'Get started quickly' bit) you can't see what you've selected.
It looks like the "Try it out" is chasing the mouse, but perhaps someone tried to get a bit too fancy with it. Any mouse movement that is slightly irregular (speed, circular motion, etc.) makes for really wonky animations.
