1-line bug (--plot-background: white;)

Thanks for your amazing library. We're super excited about it!

This line of this commit was a mistake, right?

I know it was meant to address #1434.

Line 261 in 17ed038

--plot-background: white;

I assume what we want is:

  background: var(--plot-background);

Right now, my tooltips look bad when my app is in dark mode (because the --plot-background gets overridden to white for this SVG.

If you have any quick tips for how to resolve, I'd appreciate it.

Thanks.
