I'm sorry if this has already been covered but I couldn't see any posts on it.
Is there any reason that the 'Preview Post' function on the desktop site is now crammed into a single column/half page on the display? (ie not spread across the Preview box.) It's difficult to read and doesn't now show an accurate representation of what the final post is going to look like. It's been doing it for over a week.
(I'd post a screenshot but they're a bit difficult at the moment.)
