Panning is doing inverse when sort is set to descending

[mattijn]

Given the following minimal spec:

{
  "$schema": "https://vega.github.io/schema/vega-lite/v4.json",
  "data": {"url": "data/cars.json"},
  "mark": "tick",
  "encoding": {
    "x": {"field": "Horsepower", "type": "quantitative", "sort": "descending"}
  },
  "selection": {
    "zoompan": {"type": "interval", "bind": "scales", "encodings": ["x"]}
  }
}

And this animated gif:

I was hoping that the panning remains in line with the mouse movement. But it is not. Now, because of the "sort": "descending", the panning-movement is the inverse of the panning.

Thanks. Also a related bug, using scale.reverse is similarly problematic:

{
  "$schema": "https://vega.github.io/schema/vega-lite/v4.json",
  "data": {"url": "data/cars.json"},
  "mark": "tick",
  "encoding": {
    "x": {"field": "Horsepower", "type": "quantitative", "scale": {"reverse": true}}
  },
  "selection": {
    "zoompan": {"type": "interval", "bind": "scales", "encodings": ["x"]}
  }
}
