Title: Removed unneeded reference to `window.event`. #12610

The need for `window.event` does not seem to be present for the current
set of support browser/platforms. Use of `event || window.event` syntax
seems only relevant when attaching event listeners via the following
syntax:

document.body.onclick = function(event){
var e = event || window.event; // event is null in the case of IE6
...
}
