The browser will play it for the requested duration. Of course, this may 
mean extra frames in between the ones specified in the rule. As currently
designed, this is a feature of CSS Animations, not a bug.

It's possible there is a use-case for animations where the developers
specified a frame rate and defines each frame i.e. there is no interpolation.
I am not sure this could be just an additional property or an extension on
the current @keyframes, however.

It would be helpful to see such animations as exported.
