The following code worked on jQuery v1.6.4

$('mydiv').delegate('seconddiv','hover', function( event ) {
    // do something depending on event.type
});

Using the current 1.9.1 the event never gets fired. If i use mouseenter mouseleave instead of hover it works as expected.

I tried both the delegate() and the on() function with same result.

Here is an example using jQuery v1.8.3: http://jsfiddle.net/UQ5p7/ -> it works as expected. Here the exact same thing with v1.9.1: http://jsfiddle.net/djS8g/1/ -> nothing happens at all.
