2007 - floats being overwritten

Status: VERIFIED FIXED

Your checkin regarding what goes on top of what seems to have messed up my
homepage.  It worked wonderfully for everything else (i.e, nontransparent
backgrounds).  The right floating images are now drawn over by the P element
next to them, *which has a transparent background*.  (See bug 1413 for related
event problems.)

Similar problems are reported in bug 1910.

You should follow CSS2, section 9.5:  "When an inline box overlaps with a
float, the content, background, and borders of the inline box are rendered in
front of the float. When a block box overlaps, the background and borders of
the block box are rendered behind the float and are only be visible where the
box is transparent. The content of the block box is rendered in front of the
float."  Handling the events this way should also solve the event problems.

Right now, to see this bug, you need to use a stylesheet that puts borders on
the IMG elements that are links (or, rather, doesn't take them away) and *also*
puts background-color on the P elements.  You can simulate this by putting
STYLE="background: black;" on the P element after the three images to see the
problem.

The handling of this problem has changed a bit over time.  Right now you are
drawing the inline content of the float over top of the background of the
non-float, but not the borders within the float or the background of the float.

There are better test cases for this problem in bug 1277, and also 1910.  Bug
1413 is probably related.

Really a dup of 1277, but fixed today anyway

Using 3/26 build, verified fixed. Floats are correct.
