The group discussed this issue.  We don't see any specific references in
the mentioned section saying that the background area is a rectangle.
And since this section refers to CSS's definition of backgrounds which
says that some of these issues related to inline elements are undefined,
we don't see the need to repeat that they are undefined.

The group discussed this yesterday in our discussion of [1] and also
came to the conclusion that it should be specified in CSS, and I'm
planning to send a message shortly raising an issue on CSS 2.1 regarding
undefined behavior for scalable background images.
