Bug 6619 – Affects delta.com: getting and setting cssText property not supported for rules (only style decls)

• Status: RESOLVED
• Resolution: FIXED
• Component: JavaScriptCore

This bug is also in Radar as <rdar://3486985>

Getting and setting cssText does not work with rules, even though I recently made it work for style 
declarations. I don't have a test case for this yet, but am filing the bug to remind myself.

<rdar://problem/4199876> indicates a problem with the rendering of http://www.delta.com

The problem appears to be that they try to set cssText. It is failing at the following line in one of the 
Javascript files:

if(document.styleSheets[i].cssRules[j].cssText.indexOf("img") != -1)

And consequently does not trim the repeated images. I have attached a reduction of delta.com....it can 
probably be reduced more, but this is clear enough to see the problem. I added two alert boxes 
too...only one will appear in Safari because it aborts the Javascript before the second. They will both 
appear -- twice, in fact -- in Firefox.

Reduction.

The cssText problem is not visible in ToT. However, sometimes getting CSS shorthand properties doesn't 
work. I've attached a fix for that in #6653

This does not fix the rendering issue though. I've come up with a reduction that fails to render correctly in 
Firefox and Safari but works in WinIE.

Better reduction

Yet another reduction

Here is a slightly simpler reduction. WinIE ignores the 6 pixels on padding and pink div cuts off right at the bottom of the image. Safari and Firefox honor the padding. I am not sure why WinIE knows to ignore it. Also, if you make a simple adjustment, like remove the font-size style in the css, then WinIE honors the padding too, and the pink div sticks out the bottom. Crazay!

Closing, since the site has changed to not longer have this bug, and we don't want to make a change to work with the old site, because that would require breaking the CSS box model.

whoops, putting it back for tracking purposes.
