tooltipText: Preserve x value type

[GollyJer]

First... I'm so happy to have found this package. It's so simple and fast. Thank you!! 💯
I came to ask about snapping the tooltip to exact values and it looks like 50% of the other issues are asking the same thing. 🤪
So I'll refrain from asking that again.

The other question I have, which must be related, is how to get the actual x value into the tooltip if it's a Date?

We have a SlideAreaChart with data looking like this:

data: {
    x: Date;
    y: number;
}[];

and the prop xScale="time".

However, when we try and get the x value in the tooltip it comes back as a number.

toolTipProps={{
  toolTipTextRenderers: [
    ({ scaleY, y, x }) => {
      return {
        text: `${scaleY.invert(y).toFixed(1).toString()} ${x}`,
      };
    },
  ],
}}

Is there a way to get the x value into the tooltip exactly as passed in?

Thanks!
