XHTML and SVG namespaces in createElementNS and getElementsByTagNameNS

[FranklinWhale]

When XHTML namespace is passed into createElementNS, a HTMLElement should be returned. There has been a similar overload for SVG.

When XHTML namespace is passed into getElementsByTagNameNS, a HTMLCollectionOf<HTMLElement> should be returned. Similarly, when SVG namespace is passed into getElementsByTagNameNS, a HTMLCollectionOf<SVGElement> should be returned.

Also, according to the DOM Standard, getElementsByTagName, getElementsByTagNameNS and getElementsByClassName should all return HTMLCollection. Edge, Firefox and Chrome all follow the standard.

I note that there are lots of overloads for getElementsByTagName. I am not sure whether I should do the same manually for getElementsByTagNameNS.
