Bug report: there is something wrong with the slider below the chart in the million-points example:

While dragging, the slider does not stay under the cursor, but instead moves by unexpected distances.

Thanks - you're the second person to report this! Same issue as the Mac M1 scrollbar bug reported earlier.

Looks like the data zoom slider has a momentum/coordinate mapping issue. Bumping this up the priority list since multiple people are hitting it.

I also experienced this behavior :)
