Quirksmode: Ignores media types in stylesheet PIs

• Component: CSS
• Status: RESOLVED FIXED

[David Kilzer (:ddkilzer)]

Safari ignores specified media types in stylesheet processing instructions. It loads all stylesheets instead.

Reported on 27 September 2006.

Test page: http://kennygraham.net/wsg_cssd/safaribug/  [BROKEN]

Tested on locally-built debug build of WebKit r18399 with Safari 2.0.4 (419.3) on Mac OS X 10.4.8 (8N1037).

[David Kilzer (:ddkilzer)]

WebKit supports CSS3 media queries as of r14779.  Safari 3 in Mac OS X 10.5 Leopard as well as the Safari 3 Public Beta in 10.4 Tiger both include this support.  I believe that fixes this issue.

No this is _not_ fixed.
Here is a test case:
http://dev.l-c-n.com/XHTML/test1-multistyle2.xhtml
(the original test case is missing).
Compare the rendering in WebKit/Safari 304 with what Gecko & Opera 9+ do.
WebKit applies all stylesheets, inclucing the media print one. It shouldn't.

Please reopen.

(and note: WebKit seems to treat this file as being in quirks mode, while it should treat it as standards mode. It is served as application/xhtml+xml)

[David Kilzer (:ddkilzer)]

Thanks for the test case, Philippe!  Reopening bug.

Test case from Comment #2

The bug is that the "alternate" and "media" attributes of <?xsl-stylesheet?> tags in an application/xhtml+xml document are ignored, and all stylesheets are loaded.

If every stylesheet listed defines the same selectors, you get into a "last one loaded wins" situation (which is the case in this test case--try reordering the <?xsl-stylesheet?> tags).

Here is another web site that demonstrates the same issue:  http://www.reiermeister.de/

Moved from bug 18657

This patch is moved from bug 18657, that is clearly a duplicate and this one is older:) It fixes the attached testcase to this one, unfortunately the original
bug testcase in quirksmode site seems gone.
Cheers,

Rob.

Great!  r=me.  However, I would prefer that you fix setMedia to take a PassRefPtr while you're in that code.  It takes a raw ptr, but does take ownership of it (so your code doesn't leak) but at first glance it looks like it does.  setMedia pre-dates PassRefPtr I think.

[Rob Buis]

Landed in r32719, including the PassRefPtr tweak.
