Details 
Go to the mentioned url. You'll see a the gif running through the date.
Explorer and navigator do not do this.
Confirmed: the "sep_line.gif" IMG is displayed over the bottom half of the
text "August 11, 2000" at the top of the frame; everything else below is moved
up the same amount. Tested with the 2000-08-11-08-M18 nightly binary on WinNT.

Resummarizing from "Gif is displayed throug text" to "Gif appears over text in 
DIV with only margin-left property"

The relevant part of the html code is:
  <HTML>
  <HEAD>
  <LINK REL=STYLESHEET TYPE="text/css" HREF="/style.css">
  </HEAD>
  <body leftmargin=0 topmargin=0 vlink="#575759" text="#000000" 
  bgcolor="#CECE9C" alink="#0000ff" link="#00008b">
  <DIV class=welcome>
  <NOBR><FONT class=date>August 11, 2000</FONT></NOBR>
  </DIV>
  <IMG SRC="/images/menu/sep_line.gif" HEIGHT=6 WIDTH=130>
  ...
  </body _parsed>
  </HTML>

And the relevant fragment from "/style.css" is
  DIV.welcome { margin-left: 10px; }

David: this looks like something similar to one of the bugs marked "[MARGIN-C]"
but I'm not going to try to decide if I've found a DUP. Please resolve this
as a DUP if it is...

Summary: Gif is displayed throug text → Gif appears over text in DIV with only margin-left property
The MARGIN-C bugs are margin collapsing, which is for vertical margins only. 
I'll look at this more later.
This looks like a problem with the quirks-mode inline box model.  Assigning to
myself for further investigation, although I'm not sure I'll have time.

The quirks mode inline box model is working as I expected it to.  So I don't
understand (after 2 minutes of poking around) what Nav4 and IE are doing.  Any
thoughts?
massive update for QA contact.

(We display the testcase per the specs, so changing css1 to compat.)

dbaron: *shrug* Looks like IE is even more quirky than we imagined. Do we really
care that much? There's a simple work around -- don't say line-height:0. I don't
see any advantage to saying that anyway. WONTFIX?

I don't think it's per specs, but it's per our understanding of quirks mode. 
Since we're not going to have time to look at this before we ship, and after we
ship we'll have already set a precedent, marking WONTFIX.  Considering this is
the only known bug report on this issue, I don't think it's going to be common.
