I'm inclined to say don't call .is() on a window. There isn't really a useful result that can be given in this case since windows cannot be selected with a selector. I'll let someone else on the team weigh in before closing.

Spoke to rwaldron. This is probably easy enough to fix and I can think of at least one case where it would be nice to have this fail silently. That is, if window is part of a larger set and the set is being filtered. Assigning to myself as this is an issue in sizzle.

Easy fix, l.4352 should be:

-return (match === "*" && elem.nodeType === 1) +return (match === "*" && elem.nodeType === 1)
elem.nodeName.toLowerCase() === match;
(elem.nodeName && elem.nodeName.toLowerCase() === match);

It was broken for elements which does not have a "nodeName" property.

Resolution: fixed
Status: assignedclosed

Override Sizzle attribute retrieval with jQuery.attr. Fixes #5637, #7128, #9261, #9570, #10178.

Bug fixed on the side: $(window).is('a') was throwing an exception. Fixes #10178.
