RenderTable::paintBoxDecorations shouldn't do the BackgroundBleedAvoidance optimization if the table collapses borders paintBoxDecorations is doing the BackgroundBleedAvoidance optimization if the element's opaque solid rounded borders obscure border edges. However, if a table collapses borders, it doesn't paint the borders. We should use the optimization.
