No particular reason to spell out const here explicitly.

Instead of exposing the maps, perhaps you could just have 

RefPtr<CSSTransition> Element::completedTransitionForProperty(CSSProperty)

Seems like that's the only thing these are used for and it would simplify the call sites.

Or even just

bool Element::hasCompletedTransitionForProperty(CSSProperty)

?

Solution is to just remove the unnecessary variable declaration... OK?
