It's a bit of waste, and as the code is single threaded, it could be shared.  However, CSS calculations are cached already, and so this probably won't do anything.  Keeping this PR focused on the fix seems better.  

If we're gonna optimize, I think it would be better to do some measurements first to see if there is at least 1 ms or more to win anywhere.
