Consider this situation: When a user types some text into paragraph 2, it may
change the styling in paragraph 2, 3, 4, ...
Will the createRichParagraph - method be called for each paragraph after each
typed character? That would probably be inefficient; On the other hand, if it
is only called for the paragraph the user typed in, that may not be enough.
