Interesting, looking at mdn and the spec, it seems like the name comes last, however, reading a bit more into the spec, it doesn't really matter the order. It'll basically try its best to parse things. So, I think that the tool isn't right here. It should be able to parse it out properly. However, it does seem like we already have the name as the first item in a few of the other animation properties, so, we may as well be more consistent.
