The old HTML parser doesn't do invalid-markup fixup on this testcase, so doesn't create an <tr> kids of the <thead>; instead the <th> are just kids of the <thead> directly.
The HTML5 parser creates a <tr> kid in this situation.
This is fixed in trunk; we're not going to change the behavior on the 1.9.2 branch.
