Instead of sifting through the layout tree to extract the selected text, look at the DOM selection instead. Note that we can't just stringify the DOM Range, as that would include non-visible things (like the content of <style> elements, etc.) so we run it through an ad-hoc variant of the range stringification algorithm. This can probably be factored better, but it's a start. :^)
