183380 - positioned <object>'s backgrounds get painted over contents

Status: RESOLVED DUPLICATE of bug 180502

(Core :: Web Painting, defect)

Description

[Hixie (not reading bugmail)]

See http://www.hixie.ch/tests/adhoc/html/object/003.html

An <object> element with position:absolute and a non-transparent background
renders its background on top of the contents of the <object>.

Also occurs for:
   position: relative http://www.hixie.ch/tests/adhoc/html/object/004.html
   -moz-opacity: 0.5  http://www.hixie.ch/tests/adhoc/html/object/005.html

Doesn't occur for:
   overflow: hidden   http://www.hixie.ch/tests/adhoc/html/object/006.html
   overflow: scroll   http://www.hixie.ch/tests/adhoc/html/object/007.html

Assigning to views since bz and dbaron seemed to think it was a views ordering
problem. Seems likely.

This made me think of bug 182874, although it's a somewhat random connection.

This was originally spotted on http://www.tantek.com/log/2002/12.html, but that
page has since been changed to not explicitly set a background on the <object>
element in question.

This bug is fixed by my patch in bug 180502.
