It is unrelated to 44498. I've been investigating this and the parser introduces an empty <td></td> when parsing {{Certification Table Top}}. This doesn't happen when I copy the wikitext verbatim and parse it on its own. So, just an edge case which should be fixable relatively easily.

Based on ssastry's commment, I went ahead and did a "subst" on "Certification Table Top" and "Certification Table Bottom". It got worse: http://en.wikipedia.org/wiki/User:Kww/certtablesubst?veaction=edit and http://parsoid.wmflabs.org/en/User:Kww/certtablesubst

The subst-related parse issues are unrelated to the bug that we are fixing here. But, the patch above deals with the empty-cell scenarios that break the table on the Metallica album page.

Change 76842 merged by jenkins-bot:
(Bug 52296) Delete empty autoinserted tags in the last DOM pass

https://gerrit.wikimedia.org/r/76842

This fix has now been deployed and verified that User:Kww/certtable now shows up correctly in VE.

I am going to reopen Metallica album page for editing.

Closing -- please reopen if you see a problem.

Please don't reenable editing on that page until 52254 is also fixed.

Yes, I noticed the other related bug and didn't re-enable it. I meant to update the bug report, but I got sucked into verifying other bug fixes.
