Re: [csswg-drafts] [css-overflow-5] What is the active :checked marker when some markers point to elements within different scrolling containers? (#11098)

> Hm, for the ancestors case I've seen both behaviors; for example, in a ToC scroll indicator, I've seen both "just indicate the single most relevant entry" and "indicate the most relevant entry and all ancestors, since you're also in them"; I think the latter is sometimes done with a slightly different styling on the ancestors.

Wouldn't the most common way developers would style the ancestors of the inner active marker be with `:has`, e.g. something like
```css
.target:has(.target::scroll-marker::target-current)::scroll-marker {
  /* Style ancestor markers of the current scroll marker */
}
```
