Yeah, that sounds familiar, because thats exactly what I'm working on 
currently. 

do you have some code to share already? I've made some experiments but no 
concrete idea on the best implementation for this yet. We've tried hard to 
avoid giving the CSS line boxes an actual representation in the rendertree 
so far, and I hope we can keep it this way.

ugh. do we have to implement this detail? anything major website that 
breaks?

Yes. don't forget to look at the code in HEAD, I remember a few 
related bugfixes.

I'm not sure I understand. All inlines inherit currently RenderBox, so it 
just requires storing the static position offsets during bidi positioning 
in the box. 

Is this what you mean?

The problem is this doesn't work for background-positioning of nested 
inlines. I've no solution for that yet.
