201284 - image placeholder not repainted on reflow

Status: NEW

(Core :: Web Painting, defect)

Description

[Andrew Schultz]

I'm seeing this bug with linux trunk 20030408
If your build triggers the upgrade nagging on the start page, and the download
button image is not cached, the placeholder for the download button is placed a
bit too far to the right (left side of the placeholder is where the right side
of the image should be).  When the actual image is retrieved, it is displayed in
the correct position.  However, part of the original placeholder is not removed
(the part outside the image's padding).  Moving a window over the area forces it
to redraw and the placeholder is gone.

This problem only occurs in standards mode.  In quirks mode, the placeholder is
drawn with the right side where the image's right side ends up.

testcase and screenshot to follow.

If this bug were still present, it might have been fixed by bug 409870.  However, I don't see it in a build before that patch.
