[selectors] "Match a selector" vs. ordering and pseudo-elements

Hi,

Selectors 4 defines a "match a selector" algorithm [1] (used in DOM for 
selectors APIs [2]), but itís obvious what happens to pseudo-elements in 
this algorithm. DOM expects a list of elements (only) as a result.

"Append each element in single result to result" seems to imply 
excluding pseudo-elements in the process, but that should be explicit.

(This issue was originally in [3], but it now looks like Selector 4ís 
text needs a bit of tweaking.)

Also, I *think* that elements in API results are expected to be in 
document order, but Iím not sure that the algorithm as written in the 
current ED ensures that.
