[css3-animations] Handling multi-valued animation-timing-function inside a keyframe

When used inside a keyframe, the animation-timing-function defines the progress
of the animation between its keyframe and the next.

As noted by David[1] in the mail referenced by bug 14796, the property does accept 
a list of values. When this occurs inside a keyframe we could either ignore the
animation-declaration or use the first specified value.

Gecko and IE10 use the first value and ignore the rest. WebKit appears to use the last.

Thoughts?
