Use CorrespondingUseElement() in SVGElement::TreeScopeForIdResolution

Use CorrespondingUseElement() in SVGElement::TreeScopeForIdResolution

For elements sourced non-locally, CorrespondingElement() will give the
TreeScope of the document it was sourced from rather than the TreeScope
of the <use> element. Until we are able to resolve references at
ComputedStyle resolution, attempt to use the host of the shadow tree,
i.e the (outermost) <use> element. (This will not work when external
paint servers are supported, or with a paint server defined in the
referenced document.)
