Description

In jQuery 1.6 and after (tested in 1.6, 1.6.4, 1.7, 1.7.1) feature detection:

$.support.style returns false.

Versions before 1.6 (tested in 1.5.2) returned true.

Bug is still present in latest 1.7.1 release.

This is not a bug, the bug was actually in 1.5.2.

From the docs:

style is equal to true if inline styles for an element can be accessed through the DOM attribute called style, as required by the DOM Level 2 specification. In this case, .getAttribute('style') can retrieve this value; in Internet Explorer, .cssText is used for this purpose. DOM l2 Style spec

Since IE is using .cssText, it does not support the style attribute, and therefor returns false.

This was an intentional change. IE8 is buggy in a different way than IE6/7. IE6/7 will return the style property rather than the attribute and IE8 will return the attribute, but with all style properties uppercased. We normalize this.
