Description
See repro: http://jsfiddle.net/WjYWh/
One could argue that $.extend should not be expected to work with custom objects like this, but there are test cases suggesting otherwise: https://github.com/jquery/jquery/blob/master/test/unit/core.js#L898
Being able to extend such objects (their properties, anyway) would be very nice. And in any case this kind of thing should be made explicit in the docs: http://api.jquery.com/jQuery.extend/ (Currently there's a disclaimer about primitive types, but that's it.)
This issue was previously reported, but the reporter didn't follow up with a repro so it was closed: http://bugs.jquery.com/ticket/10014
I tested 1.7.1 and 1.7.2, though that fiddle is currently for edge.
