I do not agree with this. In the case of animating a sprite-sheet with
 finite iterations (background-position) it is impossible to overshoot
 due to the limitations of the underlying background-image. I think 
that possible parametrizations to animate all frames correctly with 
fill-mode forwards only exist for 1 and infinite iterations. Run the 
example here: 

Should this be a separate issue?
I think this is not an issue of intuitiveness. It appears to be 
uncharted territory in the specs, if not a specs-bug. 
Is there a link to a draft for the proposed frames() timing-function?
