test case

RenderBox::determineBackgroundBleedAvoidance returns BackgroundBleedUseTransparencyLayer for cases of no bleeding without taking background-clip:content-box into account

In the test case, RenderBox::paintBoxDecorations doesn't need to
begin a transparency layer because the background and borders
don't intersect. However,
RenderBox::determineBackgroundBleedAvoidance returns
BackgroundBleedUseTransparencyLayer because it's always assuming
background-clip:border-box.
