For the most part, people animating on the web can use transforms and 
opacity to reduce layout repaint triggers. Animating height is one of 
the most common use-cases that I've encountered where a transform 
(even scale) doesn't quite work without a lot of hacks that are fairly
 precariously balanced. (I can list the workarounds I've found if you 
would find it helpful). 

Is there any possible way to improve the rendering of height or 
max-height? I believe it would be useful for developers to have a way 
to animate height without incurring a lot jank- for accordions, 
dropdowns, and the like. Any consideration here is appreciated.
