160646 - Add back partial support for image.lowSrc

Status: RESOLVED WONTFIX

(Core :: DOM: Core & HTML, enhancement)

Description

[Alfonso Martinez]

Bug 92453 was fixed under the assumption (wrong) that only NS4 did support it,
but indeed IE also support it (due to its feature to access any attribute in an
element). And rollovers created in Frontpage (at least some versions) are based
on that attribute, so now that pages are broken in Mozilla, people is filling
bugs about it and they are being sent to Evengelism.

I think that an easier approach would be to add *partial* support for lowSrc,
that's it: don''t preload lowsrc before src, even don't preload lowsrc, don't
affect layout at all, only being able to access .lowSrc from javascript. If you
want it make it only work in quirks mode.

This change shouldn't affect page load or rendering, it should be based only in
adding a getter and a setter to the Image elements and it would fix some pages
that now are broken in Mozilla

I've only seen one site that used lowsrc in european evangelism...

If we'd get evidence that there's a significant need for this we'll re-consider,
but for now this'll be WONTFIX.

It seems that this *may* be - at least partially - addressed. Moz 1.4 and FB
07112003 both handle MS Frontpage created photo albums better (see bug 167187
for my original report). Linked photos are now displayed properly in these
albums. Granted, we still don't get a scrollable view, but that has nothing to
do with image.lowSrc.
