According to the check this site does, apparently Firefox has Chrome's new table layout engine
Given the introduction of the spec is about correctness I… guess that means they already implemented whatever the site checks for correctly?
<tr id="enabled" style="position: sticky; top: 1px; left: 0;"><th>YES</th></tr> <tr><td id="notenabled">NO</td></tr>
should just say if you still have the Chrome table rendering bugs or not.
