Yes. If I change the bg color, I can see that there is another box on the next line that is not physically connected to the first. So it is not unreasonable to treat it separately  The reason I would do so, with per-line transformations within a single element, is so that transform-origin gives reasonable results for :hover-ed text.

Yeah, I'm in the same boat (with my Fu poking).

Right. And there it would be even more evident that you'd want two different origins for the transform, if you are using it to call attention to text that is being hovered. You don't want the text to jump away from the cursor, you just want it to get bigger (or whatever) underneath the cursor.
