(WebCore::StyleAttributeMutationScope::StyleAttributeMutationScope): Remember the old value when this is
an inline style declaration for a custom element. Also store m_oldValue and m_customElement instead of
a mutation record so that we don't create a superfluous mutation record for custom elements.

when m_customElement is not null.
