Note that this mostly happens while we add References, otherwise page is published. This seems related to Parsoid service.
Version: master
Severity: major
Niklas: on T75121, I had added a comment indicating that if you added the about and data-mw attributes, that should work. The dom spec has been updated as well to make this clear.
Can someone confirm if this is still a problem once you fix the HTML that you send Parsoid?
Subbu, Santhosh is taking a look at this later today. He can confirm in some time. Thanks.
Change 177189 had a related patch set uploaded (by Santhosh):
Keep data-mw attributes for references to avoid parsoid error
@ssastry, I added data-mw to the references and it fixed the error. I am able to publish Santos_Colón from es after translation.
The data-mw , data-parsoid attributes were removed before sending the HTML to Machine translation engines to give them minimal HTML to work with. After Machine translation, we are now restoring data-mw for references.
