I think if you set 100% { display: block; opacity: 0; } you'd get the effect you're looking for.
The spec should say that non-animatable properties in a keyframe value rule are applied (we agreed for transitions that non-animatable properties do actually change over time, at the end of the duration). If that's not the case then I'll fix it. If WebKit doesn't implement this then it's a bug too.
So basically, I think there is a workaround, but it might not be specified or implemented :) Hopefully others agree.
