Commons' TitleBlacklist messages are huge, sometimes messy and generally not parseable by jqueryMsg for multiple reasons. This means that we can't currently display them in VisualEditor's file upload dialog.

I'm not sure if we can solve this entirely from the technical side, or if we'll need to tweak the messages. Something to investigate.
