target="_top" in embedded SVG fails to replace parent content

I'm not sure if this is an SVG issue or a more general link/object issue.

Shows how the test authors expected target="_top" to work.

This seems to be an IE thing:

Frame* FrameTree::find(const AtomicString& name) const
seems to correctly check for _top however.

Ok.  Our problem here is in SVGAElement::defaultEventHandler:

        String target = getAttribute(SVGNames::targetAttr);
        String xlinktarget = getAttribute(XLinkNames::showAttr);
        if (e && e->button() == MiddleButton)
            target = "_blank";
        else if (target.isEmpty()) // if target is empty, default to "_self" or use xlink:target if set
            target = (xlinktarget == "new") ? "_blank" : "_self";

That might be the correct behavior for xlink:show, but that's not right for :target, which should behave like html's :target attribute and correctly support _top, etc.

This will be really easy to fix if we just make a test of all the various xlink:show, xlink:target and null:target values.

The target="_top" part of this test seems to work fine these days.

Yes, I would be shocked if this didn't work today.
