Styled mode line chart series className not applied to shared tooltip

[fhoeben]

Expected behaviour

Given I have a line chart, in styled mode, with a shared tooltip
When I apply a className to my series
Then I expect that className to be applied to the tooltip element for that series

Actual behaviour

The className specified is not added to the values for the series in the tooltip

Live demo with steps to reproduce

https://codepen.io/fhoeben/pen/WNJyeNQ

The line colours have been configured, these are applied to the labels but not to the tooltip. The tooltip elements do not have the weight or bmi class specified to their series

Hi @fhoeben!

I agree the class name and new colors should be reflected in the tooltip while using the styledMode.

As a workaround, you can use other CSS selectors to change those colors- demo.

@fhoeben The safest workaround (and how coloring is intended to work), is to use the colorIndex option to handle your color-to-series mapping.
