Make chapters start on new page in reflowable ePub

I thnk you may be looking in the wrong place for the actual reason this was a fix.

If a paragraph is —

• Given a page-break setting in its style;
• Tagged as a document split style;
• and Document Split is set (using "follow paragraph settings")

— it should appear at the top of its own virtual page in [pretty much] any paginating reader. Little else affects this behavior. I'd suggest that in deleting what seemed to be an extra paragraph perhaps shifted style settings or had some other secondary affect, but what precedes a 'split' paragraph has little to do with the action.

That's pretty much how it's done in all documents, print, PDF etc.

With EPUB, though, it depends on the reader. Not all of them will break to a new screen-page on a page-break directive, because of the HTML basis for the document. It works on through to Kindle and in some small-screen readers, but if you open your doc on a full-screen reader like a browser plug-in, you won't see page breaks.
