Re: [fxtf-drafts] [filter-effects-1] What is the visual effect of filter() on the document element?

As per https://github.com/w3c/fxtf-drafts/issues/11#issuecomment-360240933 the filter *should* apply to the document element's background color. However, that comment does not mention how the default background color should be treated. For consistency with `mix-blend-mode` I would suggest that the default background color *not* be filtered. This would also make sense for the case where there is a specified opaque background color on the `html` or `body` element but the filter turns it transparent; then the default background color should be visible behind the filter.
