.parents('[attribute*=value]') doesn't work with style attribute

[pejovica]

I was trying to match a div with .parents('[style*=opacity]') but I was getting back an empty array, although the div was definitely there.

Firebug showed that jQuery is comparing "opacity" with "[object CSSStyleDeclaration]" instead of the text content of style attribute.
