VE doesn't load if Extension:CSS is invoked on a page.
Description
Event Timeline
Honestly we generally don't actually need the special CSS for general editing (it's usually random crap like restyling the TOC or changing the monobook theme or mimicking enwp's crazy templates or something dumb like that, rarely anything that does much to the content itself), so VE might as well just skip over it and edit the page as if it weren't there?
I don't have VisualEditor setup anywhere. Can you provide some additional details on what the error is?
Maybe a screenshot of the failure and/or details of any errors in the JavaScript console.
You know what, this appears to be a browser-specific problem (oldopera), so nevermind. In firefox VE does just treat it as a weird template and ignore the content. Which is... fine.
Might be worth adding a task to make it actually *work*, but that's a separate issue.
