Run processors on whole of text (#16155)
There is an inefficiency in the design of our processors which means that Emoji and other processors run in order n^2 time. This PR forces the processors to process the entirety of text node before passing back up. The fundamental inefficiency remains but it should be significantly ameliorated.
