97033 - stylesheets linked with titles are loaded as alt stylesheet

Status: VERIFIED INVALID

(Core :: CSS Parsing and Computation, defect)

Description

[basic]

given a HTML page with

<link rel="stylesheet" title="stylesheet 1" href="style1.css">
<link rel="stylesheet" title="stylesheet 2" href="style2.css">
<link rel="stylesheet" title="stylesheet 3" href="style3.css">

mozilla (build 2001082008) gives "stylesheet 2" and "stylesheet 3" as alternate
stylesheets!! I'll make a testcase. Note that the correct way to do alternate
stylesheets:
<link rel="stylesheet" title="stylesheet 1" href="style1.css">
<link rel="alternate stylesheet" title="stylesheet 2" href="style2.css">
<link rel="stylesheet alternate" title="stylesheet 3" href="style3.css">
does not work in mozilla.

In testcase attachment 47158 [details] mozilla should be displaying the text "stylesheet
3" in blue and monospace font.

I forgot to mention that what actually happens is that "stylesheet 1" is
displayed and in the View->Use Stylesheet menu I see none,"stylesheet 1",
"stylesheet 2" and "stylesheet 3".

Our behavior is correct.  See
http://www.w3.org/TR/html4/present/styles.html#h-14.3 .

In particular, see the following two statements in 14.3.2:

"          * To make a style sheet persistent, set the rel attribute to
"stylesheet" and don't set the title attribute.
          * To make a style sheet preferred, set the rel attribute to
"stylesheet" and name the style sheet with the title attribute.
          * To specify an alternate style sheet, set the rel attribute to
"alternate stylesheet" and name the style sheet with the title attribute."

"If two or more LINK elements specify a preferred style sheet, the first one
takes precedence."

Marking bug as INVALID.  See the tests at
