For an HTML document, yes -- but the behavior in question (that we'd be mimicking here for filters) also involves the `<body>` element and the viewport.  Here's the spec text for the behaviors that Markus was referencing for `overflow` and `background`, with more concrete definitions/explanations:

https://www.w3.org/TR/css-backgrounds-3/#body-background
