I would have to double-check the proposed spec, but I believe the  
transition-related property values at the time a transition begins are  
used for the whole transition. However, it is somewhat underspecified  
in the proposal when exactly a transition begins. In our experimental  
implementation, it begins at style resolution time but we feel this  
may be too unpredictable for authors, for animations triggered from  
script, since getting style values can trigger a style resolution.
