Log Message:
-----------
HTMLFastPathParser fails to detect nested <li> elements when outer <li> is
parsed via parseSpecificElements
https://bugs.webkit.org/show_bug.cgi?id=311342
Reviewed by Ryosuke Niwa.
The m_insideOfTagLi guard that prevents nested <li> (which requires
auto-closing per the HTML spec) was only set in parseElement(). When
<ul>/<ol> parse their children via parseSpecificElements<Li>(), the
outer <li> bypasses parseElement() entirely, so m_insideOfTagLi is
never set. A subsequent <li> inside that outer <li> is then incorrectly
accepted as a nested child instead of causing the fast parser to bail
out.
For example, "<ul><li><li></li></li></ul>" produced nested <li>
elements instead of the spec-required sibling <li> elements.
Fix by adding a parseChild override to the Li tag struct that sets
m_insideOfTagLi while parsing children, mirroring the existing pattern
used by the A tag struct for m_insideOfTagA. Uses save/restore (rather
than unconditional set/clear) because <li> can legitimately nest
through intervening <ul>/<ol>.
