Bug#670937: libwebkitgtk-1.0-0: Invalid background image + border rendering

Mon Apr 30 15:12:46 UTC 2012

Package: libwebkitgtk-1.0-0
Version: 1.8.1-1
Severity: normal

Dear maintainers,

The following HTML/CSS snippet renders wrong in WebKit (but just fine with
Gecko):

######## bug.html begin ########
<!DOCTYPE html>
<html>
  <head>
    <title>Page</title>
    <style type="text/css">
      html {
        border: 1px solid black;
        background-image: url('img.jpg');
      }
    </style>
  </head>

  <body>
    <h1>Page</h1>
  </body>
</html>
######## bug.html end ########

The expected result is the whole page to have "img.jpg" as the background,
and a thin solid black border around "Page".

The actual result is a plain colored background with a somewhat random
color, apparently coming from the image.  This color is always the same
given the image is the same, but is different with each image.  The border
renders fine.

There are a few things that makes the image render OK:

* removing the border (in any way that prevents it from being rendered,
  from removing the declaration to setting its width to 0 or messing up
  the declaration);
* applying the style to <body> and not <html> or <h1>

Please note that this bug appears both in Epiphany (WebKitGTK+3.0) and
geany-plguin-webhelper (WebKitGTK+1.0).

Regards,
Colomban
