Sorry for the late answer. As HTML was truncated and, therefore, changed, Ruby required additional sanitization to ensure that everything was still okay. I'll move truncation method in the `RichText::Base`. I think, it will solve most of problems and additional complexities introduced by adding this method to the concern.
