After some testing:

2d.pattern.image.incomplete.omitted:
works after checking image->src().isValid()) before creating pattern

2d.pattern.image.broken:
needs knowledge of whether image really is decodable

2d.pattern.image.incomplete.empty:
the image url used in createPattern() ends up as the _page_ url because HTMLIMageElement does document().completeURL(). This would still work with knowledge of whether image really is decodable
