I'd like to see a better reason that "the name threw me off" before considering renaming animation-fill-mode. The term is has been used in SMIL and SVG animation since < 2000, Microsoft's WPF since (approximately) Vista, Core Animation since OS X 10.5, and probably many other places as well.

I think people familiar with animation will understand the meaning.
