It doesn't work when ancestor element has overflow-x: hidden

I found the issue it doesn't work when ancestor element like `#container` has the style `overflow-x: hidden`.

Please see this demo: https://wonderful-minsky-c230e6.netlify.com/ ([source](https://github.com/sundaycrafts/weypoint-demo/blob/master/src/App.js))

Can I help me to solve this issue?

Reproduce the failure using the linked Netlify demo and inspect its source in src/App.js. Compare behavior with and without the ancestor’s overflow-x: hidden style; done means the waypoint callback works correctly in that scenario.
