jQuery custom object event handler exception-swallowing regression test case

Demonstrates a regression caused by the fix to jQuery bug #3533. Exceptions thrown in the final `on<event>` handler of a custom object will be swallowed by jQuery.

HTML

Check your console.  The error <code>This exception will be swallowed</code> <i>should</i> show up, but the thrown exception is improperly caught by jQuery-1.5.js:2452.

JavaScript

var Test = function() {
    this.onclick = function(e) {
        console.log('Running onclick');
        throw new Error('This exception will be swallowed.');
        console.log('...and execution will stop.');
    }
    this.onsubmit = function(e) {
        alert("This won't run because the exception in the bound handler will throw properly.");
    }
}
var obj = new Test();
$(obj).click();
$(obj).submit(function() { throw new Error('This will throw'); }).submit();
