Yes, I am aware of that. I spent a year creating a CSS Regions based book
layout engine ( http://fiduswriter.github.io/pagination.js/ ) , so I am
absolutely interested in fragmentation coming back one day. In the meantime
I have created an ad-hoc solution using CSS columns (
http://fiduswriter.github.io/simplePagination.js/simplePagination.html )

The main difference is that the CSS fragmentation based version allows to
combine it with contenteditable (text flowing from page to page while
editing/writing it). Using Javascript/CSS multicolumns to create the same
design means cutting up the DOM, so it has to be done after the text is
written. We switched to this second approach when it became clear that CSS
Regions would be removed from Chrome.

The way we handle it is to let the user write the text in one large page
with the footnotes off to the right. When the user hits CTRL+P, the current
contents of the edited doc are copied, the original contents is hidden and
the copied version is cut up into individual pages. By the time the user
gets to the print preview, page numbers, headers, table of contents,
footnotes, etc. have all been put in place. Fragmentation would be great to
have, but for now I would already sleep much better if we would have a more
solid selection/caret-moving base to build upon.

For example a blog may decide not to allow any inline-css styling. And to
emphasize words they may only want to allow bold and italics, but not
underline and not a combination of italics and bold on the same word.

Of course visually this may be achievable using a lot of !important
statements in a general css file for the page. But the contents will turn
messy and if users copy  from a social media site to a word processor to a
blog, and from there to another blog and then into their html-based email
and then into another blog... things will end in disaster for certain at
some point.
