    resolved fdo#56772 keep track of HTML ON/OFF tokens
    
    Regression introduced with 11cbcb8b08b540b144a5df744e9fba0b6ba8144a
    followed by 56d6589368c2e88cffec0c2e518f7c90863eeae6
    
    Deep from svtools/source/svhtml/parhtml.cxx HTMLParser::_GetNextToken()
    only a HTML_TABLEDATA_OFF was generated for <td .../> without a matching
    HTML_TABLEDATA_ON (actually same for all <XXX/> ON/OFF tokens). This
    confuses a state machine that doesn't keep track of such unexpected
    closures and also expects all attributes of an element at an ON token.
    Only the parser knows this is actually one token but needs to generate
    separate ON/OFF tokens.
    
    These bugs mentioned in the original code and commits are still fixed
    with this change:
