jQuery.css(name) returns inconsistent results

[skyde]

jQuery.css(name) returns inconsistent results depending on whether name is written camel-cased or hyphened, when !important style rules apply.

To repeat:

1) add a !important style rule to an element, for example background-color: #000 !important

2) change the property with jQuery, for example $(element).css('background-color', '#fff');

3) $(element).css('background-color') returns now #000, while $(element).css('backgroundColor') returns differently #fff

Firefox 3.0.7, Opera 9.52 and IE7 were tested to work this way, on webkit-based browsers (Safari 4 and Chrome 1 tested) $(element).css() overrides !important rules with both writing styles.

I don't know which one is the correct way (styles applied with $.css can be seen as inline styles, in which case they should be overridden by !important rules), but $.css should return consistent values in any case, not depending on writing style :)

I can't reproduce this:

there seems to be no odd reporting for $.fn.css() using one or the other. Also, !important styles should remain as they are, well, important.

Checked in chrome 10, chromium 11, ff3, ff4, opera 11, safari 5, ie6-9rc1, and even on my iphone. All works as expected :D

Azatoth: your pull was landed, but is causing fails in firefox 4 and opera 11.01.
