[LBSE] Assertion failure for SVG resource containers with a namespace prefix
https://bugs.webkit.org/show_bug.cgi?id=322357
Reviewed by Patrick Griffis.
Creating the renderer for <svg:filter> fires an assertion:
ASSERTION FAILED: SVGElement::isResourceContainerTagName(element.tagQName())
Source/WebCore/rendering/svg/RenderSVGResourceContainer.cpp(47)
...
A tag can be written with a namespace prefix, as in <svg:filter>. Two
QualifiedNames are only equal when their prefixes match as well, so
<svg:filter> is not equal to SVGNames::filterTag. isResourceContainerTagName()
looked up the whole tag in a HashSet<QualifiedName> and thus missed every
prefixed resource container. Element::hasTagName() gets this right by calling
QualifiedName::matches(), which compares the local name and the namespace and
ignores the prefix.
Fix debug assertions in svg/dynamic-updates - covered by existing tests.
