Check the setup above. Make scrollBar: false to check how the animation is expected to work. But it's not working when scrollBar is true. The documentation does not mention scrollBar: false and easingcss3 as incompatible so I assume this is a bug.
Latest version and all browsers.
P.S. Am I supposed to publish a fiddle with my license key inside? I purchased it yesterday but don't feel comfortable with the idea of displaying it publicly in the fiddle. I'll update it if it's required for support requests.
The animation taking place when using scrollBar:true is not fired by CSS 3 but by Javascript instead.
There's no way to fire a real page scroll (with scrollbar) using CSS.
Therefore, the use of css3:true there won't have any effect. It is exactly the same as using css3:false and therefore the easing you have to use will have to be placed under the easing option and not the easingcss3 one.

Notice I also imported the file vendors/easings.js

The key is not required for the fiddle :)
No worries! 😉
Thank you very much for the detailed explanation and the demo. Makes perfect sense now.
