[CSS21] Text and overlapping with negative margin-bottom

Hello,

I am confused and surprised by this test

http://www.gtalbot.org/BrowserBugsSection/css21testsuite/Text-negative-margin-bottom.html

I'd like to know where in the CSS 2.1 spec the resulting layout is explained.
Why am I able to read the text of div#overlapped?
What am I missing here?
