ISSUE-22: The position of a background on pages of unequal width

bg-break bounding-box

The position of a background on pages of unequal width

CSS3 Backgrounds and Borders
Raised by:
Bert Bos
Opened on:
'background-break: bounding-box' says that the background is drawn as if an element wasn't broken over several pages. If the background image is not repeated, there is only one copy; if it is resized, it's is resized to the size of the unbroken element, etc.

The question is what is the size of the element if the element has a different width on different pages. The width it has on the first page? The maximum of its widths? Does 'bounding-box' not apply in that case?
