596354 - Track listing not showing on iTunes

Status: RESOLVED DUPLICATE of bug 591198

(Core :: CSS Parsing and Computation, defect)

Description

[Bas Schouten (:bas.schouten)]

When going to an iTunes album list nothing is showing up in the list part. This works fine in 3.6. Overriding the user-agent string seems to make no difference. turning hardware acceleration off makes no noticeable difference.

Confimred broken, on Linux trunk build:

This regressed sometime between b2 & b5:
Mozilla/5.0 (X11; Linux i686 (x86_64); rv:2.0b2) Gecko/20100720 Firefox/4.0b2
Mozilla/5.0 (X11; Linux i686 on x86_64; rv:2.0b5) Gecko/20100101 Firefox/4.0b5

Adding regressionwindow-wanted keyword to get a more targeted range.

Comment 4

[José Jeria]

Interesting:
1. view source and copy it 
2. save it to new html file
3. open html file

Result: List is visible

Comment 5

[Daniel Holbert [:dholbert]]

That usually means the error is with some resource (probably an @import'ed stylesheet) that's specified with a relative URL.

Comment 6

[Daniel Holbert [:dholbert]]

Actually, it looks like all the stylesheets are specified with relative URLs (in <link> elements in the HTML).  So comment 4 isn't particularly surprising -- it just confirms that CSS is involved here.

Comment 7

[Daniel Holbert [:dholbert]]

DOM inspector says the computed style of the span two levels up from trackname text (e.g. "The Radiance") has a computed-style height of 0 (vs a width of 77.5px).

[Timothy Nikkel (:tnikkel)]

Disabling of XUL is in the regression range, that might be the cause.

Comment 9

[Daniel Holbert [:dholbert]]

It is indeed.  This stylesheet:
  http://itunes.apple.com/stylesheets/ellipsis.css
applies an XBL binding from this XML doc:
  http://itunes.apple.com/stylesheets/ellipsis.xml
which uses XUL.

Comment 10

[Daniel Holbert [:dholbert]]

The binding applied is:
 <binding id="ellipsis">
   <content>
     <xul:window>
       <xul:description crop="end" xbl:inherits="value=xbl:text"><children/>
       </xul:description>
     </xul:window>
   </content>
 </binding>

Comment 11

[Daniel Holbert [:dholbert]]

So the bug here (if there's a bug) is that we're modifying the style based on
a "-moz-binding" style-declaration that points to no-longer-allowed-on-the-web-XUL.  Presumably we'd rather just ignore that -moz-binding declaration altogether?  (or have that visual effect?)
