This table https://en.wikipedia.org/wiki/Dancing_with_the_Stars_(U.S._TV_series)#Professional_partners was broken.
This https://en.wikipedia.org/w/index.php?title=Dancing_with_the_Stars_%28U.S._TV_series%29&diff=598301735&oldid=598141704 happened when the user just tried to add a wikilink (you can find it at the very bottom of the diff).
This edit https://en.wikipedia.org/w/index.php?title=Dancing_with_the_Stars_%28U.S._TV_series%29&diff=598390953&oldid=598363952 seems to have fixed the table (https://en.wikipedia.org/w/index.php?title=User%3AElitre_%28WMF%29%2FSandbox&diff=598393459&oldid=598393277 ).
Users are not happy, and demand that "When a "bad" syntax doesn't break the table while editing on wikitext it shouldn't break it while editing with VE either.",
"Maybe there should be some sort of Edit Notice or similar when Parsoid detects broken html."
