No, I reference the style definition above when working on my patch, but I think it's not all correct (there is no 'none' option in 'text-overflow' style). I didn't have time to trace who merge the code for what reason (it's from bug 829023). I'm intending to make it specific here, so if one day, the patch of bug 829023 getting uplift, then it won't conflict and affect my style here.
