[csswg-drafts] [css-color-hdr] How should multiple layered elements with different `dynamic-range-limit` values behave? (#11307)

weinig has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-color-hdr] How should multiple layered elements with different `dynamic-range-limit` values behave? ==
I am trying to wrap my head around how `dynamic-range-limit` is intended to work (an introduction to the property, not just an introduction to the concepts, would be helpful I think), and I am trying to work out what the intended behavior of multiple elements, all occupying the same space, one on top of another, with different `dynamic-range-limit` values should be?

If the goal of the property is to rein in overzealous dynamic ranges, choosing the lowest might make sense, but that would contradict the example given:

```css
body { dynamic-range-limit: standard; }
div.photogrid img { dynamic-range-limit: constrained-high } 
```

which indicates that the highest should be used? Or maybe it is indicating that z-order is important?

(Ultimately, this will need to be mapped to some platform concept, so if there Windows/macOS/etc APIs you are expecting these to be built on / are taking inspiration from, I would be interested to read up on them).
