Small cleanup for "Publish Series" box

Even on the biggest screen, the minute still wraps around to the next line:

@stevejburge i have a strong believe you may be testing on an older version. Please confirm this issue again after getting next version

Still there, but I'm leaving it for the next release

I believe the style may be conflicting another plugin. For example, the preview link is not suppose to float to right as in your screenshot.

So, still can't do anything on what i can't see.

@olatechpro I think this may be a Firefox-specific issue
