Scale binding flips inverted domains

[jakevdp]

If you bind a selection to scales on an inverted domain, the domain flips on first interaction. Here is an example (vega editor):

{
  "data": {"url": "data/cars.json"},
  "mark": "point",
  "encoding": {
    "x": {
      "type": "quantitative",
      "field": "Horsepower",
      "scale": {"domain": [250, 0]}
    },
    "y": {"type": "quantitative", "field": "Miles_per_Gallon"}
  },
  "selection": {
    "pan": {"type": "interval", "bind": "scales"}
  }
}

First reported in vega/altair#1693

Closing in favor of #5413 which has a few more specs that exhibit similar/related issues.

Actually, this issue occurs due to a different cause than the specs in #5413. In particular, selection-driven scale domains are read off the top-level/resolved selection signal which automatically sorts values in ascending order as part of the unioning/intersection strategy.

Fixed with #7163.
