This has been raised before, but I'll restate it here.
How should the selector be expanded in
elt.findAll("div span, div :scope span")?
The implication of :scope has to be done on a per complex selector
basis, rather than applied to the entire list. That would be equivalent to:
elt.findAll(":scope div span, div :scope span")
If this isn't to throw an error then a more complex definition is
required which can apply a different rule for implying :scope in
different parts of the selector argument. This is sure to be confusing
for anyone reading the code.
Selectors in selector lists are always independent of each other, so
authors who use a selector list would likely assume that one doesn't
affect how another in the list matches. It would seem far more
confusing for authors to do it using the other alternatives.
