User blog comment:Sarah Manley/New Editor Scheduled for Sitewide Release/@comment-161139-20110907155205/@comment-161139-20110908205929

This was happening on castleemp.wikia.com (which at the time had completely unmodified javascript -- the sites currently broken on editing due to another issue with the editor).

And after using it a bit more I see that it does replicate the small content space in its width, but I still find it much more annoying than the old preview. It was nice having the preview content at the top of the page to look at when doing complex edits, with the pop-up preview that doesn't happen.
