[Nowhere man]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; fr-FR; rv:1.3.1) Gecko/20030618 Debian/1.3.1-3
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; fr-FR; rv:1.3.1) Gecko/20030618 Debian/1.3.1-3

When a data:// URL is used in a Cascading Style Sheet, e.g. for
list-style-image, it doesn't show anything.

Reproducible: Always

Steps to Reproduce:
1. Put a data:// URL in a list-style-image property
2. Open the page

Actual Results:  
With a list-image-style property, the default list glyph is shown, with a
content property, nothing appear.

Expected Results:  
The list glyph should be replaced by the image, and the generated content should
consist of the image.

This is because you have line-breaks in the data URL's string.  If you take out
the linebreaks it works fine.  Newlines within a string have to be escaped.  See
bug 171071 and http://www.w3.org/TR/CSS21/syndata.html#tokenization

VERIFIED/dupe.

I've mailed dbaron for a clarification of the specificity of this issue, is it
CSS-only? I think it should work in HTML, but don't have time to test right now.

Additionally, there is no '//' after the 'data:', unless that is part of the
mime type.

After verification, there still remain some problems: the escaped multiline data
URL works perfectly within the CSS, but not with the src attribute of an img
element...
