Re: [csswg-drafts] [css-overflow-4] Allow scrollable overflow to be visible in the off-axis / overflow-clip-margin (#13445)

One big compat issue to note regarding proposal 2, with `visible` as the initial value, it will be extremely common that authors have specified one axis, e.g. `overflow-x: auto;` and not the other, having a specified `overflow-y: visible;`. I suspect it will not be web compatible to stop coercing the other axis in these cases. I think we can do this, but we would need to add a new initial value, e.g. `overflow: normal`, that computes to visible, hidden or auto depending on the other axis. This way we could tell when developers have explicitly specified that the other axis is visible.
