A minor change in a completely unrelated part of the article causes a copy of the broken table to be injected into the article, and a '<tr' (no closing >) is also included. Upping priority/importance as it should at least ignore elements it doesnt properly understand. The <table> was not so broken that the wikitext up to the </table> should have been ignored.

I am able to reproduce the '<tr' being added [[testwiki:User:John_Vandenberg/Table_test]], but in my test the table wasnt copied.

After fixing the syntax on enwp, the problem goes away.
