[webkit-dev] Request For Position on CSS containment

Hi webkit-dev, This is a request for WebKit's position on CSS containment. Our first interest is to implement the contain property as specified here: https://www.w3.org/TR/css-contain-1/ After that, we want to work on style containment and the content-visibility property: https://www.w3.org/TR/css-contain-2/ Regards, Cathie and Rob.
