Chrome hsla - saturation and lightness change event not fired
I am seeing an issue in the chrome picker where changing the `s` or `l` input of the hsla inputs does not call the `onChange` event.

I can reproduce on the react-color storybook, but not on the main feature/doc site.
Steps
- go to chrome story in storybook
- click through color formats in picker to get to hsla inputs
- change the lightness value
- click away from the lightness input to blur it

Expected
- onChange event was called with new lightness value, new lightness value displays as value of `l` input.

Actual
- `l` input value seems to be the same as the 'b' value in the rgba inputs.
- adding a log statement in the onChange callback shows that it is never called. When I change the 
  hue or alpha values it is called.
