> Is it possible here, that the value of ```fullyRealized``` would be still false? 

Yes, because anchors might span several pages, and it's possible that one of the pages were rendered, but some others have not.
In these cases, we create the highlights for the rendered pages, but leave the rest alone.

> If yes, should we publish the ```anchorRealized``` event in this case too?

Yes, because we still need to react to the new highlights.
