Re: [csswg-drafts] [css-contain-1] Make It easier to use contain: size in cases where the size is unknown

I see a few potential issues with that:

1. From the perspective of the layout engine I think we want to avoid 
resizing the element every time it moves out of the viewport. For 
example, that would often force the browser to scroll the page firing 
a scroll event. It'd also change the size of the scrollbars which 
would be confusing to the user. And you'd have to run resize observer.
2. It's pretty common to have JS code that queries the height of an 
element. EG imagine that for logging somebody wants to see the height 
of feed stories with videos in them. triggering resize on the querying
 of height makes the element mostly feel like it did before 
"layout-default"
