        ASSERT failure in SVGUseElement
        https://bugs.webkit.org/show_bug.cgi?id=59313

        Test case to verify webkit doesn't crash when a <use> element
        is pending on resource and the document is not well-formed.
        Test passes if no crash occurs in debug mode.

        ASSERT failure in SVGUseElement
        https://bugs.webkit.org/show_bug.cgi?id=59313

        In SVGUseElement::insertedIntoDocument(), ASSERT(!m_isPendingResource)
        was wrong because the document may not be well-formed.

        This patch asserts the element is not pending on resource or the
        document is not well-formed.
