If canInterpolate(from, to) is false, then progress should have already been set to either 0 or 1 in CSSPropertyAnimation::blendProperties(). I think you should ASSERT() that you're only dealing with 0 or 1 here and change this line to `auto& blendingRenderStyle = context.progress ? from : to;`.

Added the assertion.

I think you meant `auto& blendingRenderStyle = context.progress ? to : from;` :)
