$(window).on() breaks in IE

I've got a set of code that uses the new .on(), which I'd like to bind to the window. However, the event fails to trigger in < IE9. Example code:

This works just fine in IE

$('body').on('click', '.class', function(e){ //this really should be window instead of 'body', but IE would break
    // do stuff

This only works in FF, webkit:

$(window).on('click', '.class', function(e){ 
    // do stuff

Why do you want to bind a delegated event to window? Read the description of event delegation in the API docs for .on(), it doesn't make sense to do that.

I ran into the same issue using IE10 in Compatibility View / Document Mode: IE7 Standards.

Did not work:

$(window).on('click', '.class', function () { ( ... )

Does work:

$('body').on('click', '.class', function () { ( ... )

And again, to be clear, using $(window) for delegated events is wrong and was never supported.
