Color picker is not selecting what you click
Environment: react + react-color (2.13.8)
Demo: [https://codesandbox.io/s/xrz36m842p](https://codesandbox.io/s/xrz36m842p)

Drag circle selector from black (#000000) to white (#FFFFFF) suddenly when moving the cursor you will see that instead of only select shades of grey in the path to white, it sometimes will select other colors.

Also the bug appears when you click on that special gray colors.

**2.13.5 works well**
