Re: [csswg-drafts] [css-contain] Add contain-paint-margin CSS property (#4934)

For negative margins, I'm convinced by the argument that this would make interaction with scrollbars needlessly complicated.

So, as far as I can tell, the current consensus-in-progress is that:
- it's called either `overflow-margin` or `overflow-clip-margin`
- it takes a single value, and doesn't have longhands (but could be expanded later if need be)
- negative values are invalid
- it does not add a margin to clip-path
- it does take rounder corners into account, to avoid a discontinuity between `overflow-clip-margin: 0` and `overflow-clip-margin: 1px`
