snippet:
<span class="brownBackground">some text with <p>brown background</p></span>
... here, only "some text with" has the color defined for the <div>, but
everything within <p> has not.
Only if <p> were specified as inline element (display:inline), also its content
has the background color, as it ought to be in every case, doesn't it?

Reproducible: Always

Actual Results:  
(see Details)

Expected Results:  
child block elements should show their parent's background color.

The block box splits the inline boxes, so it's not actually inside them.  Hence
no shining through can happen.  You can put some borders on the span to see what
the boxes look like.
