Scrollbars not setted until first mousewheel event.

[ghost]

Issue Summary

Browsers tested: Chrome + Safari in mac

Current Behavior

When Scrollbar initalizes, the scrollbars and functions like scrollTo are not set until user scrolls.

Steps to Reproduce

I have a staging here -> http://www.ssll.zalo.nyc/

You can see what I'm saying in two ways:

1) Load the home (http://www.ssll.zalo.nyc/) and try to click on the arrow to scroll down. It doesn't work until you scroll a little with the mouse.

2) In the console you can play with the scrollbar instance under the var Scroll. To test it you can use the function Scroll.scrollTo(0, 50, 1700); (it only works after user has been scrolled)

I think this issue is due to dynamically inserted contents. I would suggest you call scrollbar.update(true) after appending contents.

P.S. true will force an asynchronous update (uses requestAnimationFrame).

A) I'm using scroll.update and it doesn't work in the first load.

B) the first load is not rendering dynamic contents, it's a plain php without ajax (only some images are load asynchronously, but they replace an existing low res image)

So what about calling scrollbar.update() (synchronously) in click event handler?
