101926 - width % should be calculated as relative to the containing block

Status: RESOLVED DUPLICATE of bug 97695

(Core :: Layout, defect)

This is possibly a dupe, but I couldn't find one.

The URL above has the bad practice of using a bunch of <img height=40 width=20%>
for their navbar. But instead of calculating each image's width as 20% of the
containing block, we calculate the width as 20% of ununsed space.

This is on Linux 2001092608-trunk. I will attach a screenshot.

NSCP renders this fine.  adding 4xp keyword.  (I think this is a regression, but
not sure.  Leaving regression keyword off for now)

The HTML 4.01 spec says of percentage image widths "Note that lengths expressed 
as percentages are based on the horizontal or vertical space currently 
available," a rather ambiguous definition.  However, CSS width (which applies to 
replaced elements) says that percentages are calculated in terms of the 
containing block.  Since HTML width="" is supposed to be replaced by the CSS 
equivalent, the change (fix?) proposed here makes sense...

I knew I saw this already filed.  Bug 97695.  Duping to it.
