I don't see it either, although it was resolved some time back as minuted  
in <>.

There's also a long thread (spanning multiple months) linked there,  
starting at  

One might do something like = 'block';
elem.offsetWidth; = 1;

to try to force calculation of computed values for the new box before  
modifying the property for which a transition is desired, but the exact  
details of when such calculations aren't well-defined and as the thread  
above indicates, it gets complicated.
