I really love the extracts feature, but I noted that currently all span elements are flattened out of the cleaned up HTML.
But one of the biggest usages of span tags is to mark different languages and script directions using the attributes dir and lang. These different languages are quite often present in the first line of an article on a non-english topic. I think those are thus very important elements to preserve in our multilingual content.
