speed dial demo not working for me

[davehorton]

the other demo elements work, but speed dial fails for me (in Chrome) and I see this error in dev tools:

Uncaught TypeError: Failed to execute 'animate' on 'Element': 'function (a){return a}' is not a valid value for easing

Can you link to the problem?
