Re: [svgwg] [svg-native] `overflow: scroll` is both forbidden and to behave like `hidden` (#687)

Interesting. The [initial value of `overflow` is `visible`](https://drafts.csswg.org/css-overflow-3/#propdef-overflow). 

If scroll and auto are forbidden values, one would assume that they are not allowed in conforming content, and that is a conforming renderer encounters them they are ignored (== treated as the initial value).

If that is what we want, we can fudge around things by setting a 'UA stylesheet' that sets `overflow: hidden` on the `svg` element. Which would be inline with the [special rues and uA stylesheet for overlow in SVG2](https://www.w3.org/TR/SVG2/render.html#OverflowAndClipProperties). This effectively sets the initial value to `hidden` on SVG content. Which is fine, as long as we disallow the `initial` keyword.
