I found a case which does not follow this rule (The Render container
encompasses its children dimension:

RenderBlock (anonymous) at (2,0) size 980x0 {11.00,147.00}
                      RenderInline {A} at (0,0) size 0x0
[color=#004276] {11.00,147.00}
                        RenderImage {IMG} at (956,0) size 24x27 {967.00,147.00}


The container is 980x0, but it has a child 24x27.

Not sure if the RenderBlock is 'anonymous' (like in this case) means
it break such rule.
