forked from amazingfate/loongoffice
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: https://bugs.freedesktop.org/show_bug.cgi?id=34666 https://bugs.freedesktop.org/show_bug.cgi?id=36080 https://bugs.freedesktop.org/show_bug.cgi?id=36390 Change-Id: I2b3190d297a35ee3dfda95f9a4841f7c53ed4a92
