dojo.event.browser.isEvent() doesn't check for null obj

[tim@…]

dojo.event.browser.isEvent() has the code:

return (typeof obj != "undefined")&&(typeof Event != "undefined")&&(obj.eventPhase);

Apparently, obj can be null in certain situations, so the code should be:

return (typeof obj != "undefined")&&(typeof Event != "undefined")&&(obj)&&(obj.eventPhase);

That is, it should verify that obj is not null before trying to access its properties.
