This is basically wxHtmlTagHandler except that it is extended with protected member m_WParser pointing to the wxHtmlWinParser object (value of this member is identical to wxHtmlParser's m_Parser).
Value of this attribute is identical to value of m_Parser. The only different
is that m_WParser points to wxHtmlWinParser object while m_Parser
points to wxHtmlParser object. (The same object, but overcast.)
