Details 
Mozilla 2002041709/Linux-i686, but I remember seeing it before.

Problem: no matter how wide you make the page at http://www.bellstream.de/, it
always has horizontal scroller visible. The same happens at
http://www.bellstream.com/.

Repro.: always.
Step: just visit and see.
Severity: normal → minor
Summary: horizontal scroller always visible. → horizontal scrollbar always visible.
I am seeing it on Win2K, 2002041718. What seems to trigger the bug is the
combination of a floating table with marginwidth (not supported in html4.0) set
to zero and width set to 100%, followed by a <br>:
<table width="100%" align="left" border="1">
<tbody>
<tr>
<td>foo1</td>
</tr>
</tbody>
</table>
<br>
foo2

Using the current rc2 2002051506 on Win2000 I see the same... the horizontal
scrollbar on quite a few pages, including mozillazine.  Also see it with a few
framed pages, with a particular frame having a horizontal scrollbar, and also in
the case of frames a vertical one.  About 2 weeks ago maybe more (am pretty sure
rc1 didnt have this problem) this was not happening at all.  With some sites
altering the width of the browser window by moving the sidebar tab (making it
smaller/larger) you can get rid of the horizontal scroll bar. MozillaZine.org is
one site where you can find certain positions where the horizontal scrollbar
disappears.  To me it is one of most annoying bugs around.  I have tried clean
installs, all to no avail.

    
    

    
  
Looks like the table is rounding width up to the nearest px instead of down....

The table code is correct. The issue is the 1twips BR hack at
http://lxr.mozilla.org/seamonkey/source/layout/html/base/src/nsBRFrame.cpp#183
this makes the canvas 1 twips to large and then the scroolabr appears which
doesn't do anything as 1twips is then rounded away.

Users interested in this bug may look at ShowImage extension at
http://showimage.mozdev.org/. It is made for Firefox. It didn't work very well
for me (maybe it needs updating) but it seems a good approach (no further
cluttering of the context menu for users with fast connections).
