This synthetic event is reused for performance reasons.

Getting this error in chrome console when using custom slider with 1 handle on each side.

commons.js:1342 Warning: This synthetic event is reused for performance reasons. If you’re seeing this, you’re adding a new property in the synthetic event object. The property is never released. See https://fb.me/react-event-pooling for more information.

Error alerts in this section of react:

Probably has to do with these lines: https://github.com/airbnb/rheostat/blob/master/src/Slider.jsx#L578-L579

They’re not really necessary. Want to remove them in a PR?

It’s all good. I realized my old link pointed to master so I’ve edited that as well.
