Problem when running test on yeti that relies on focus listener

[mairatma]

I've recently had problems when running tests that wait for a focus event through yeti.

For example, the test below:

    var suite = new Y.Test.Suite('my-suite');
    suite.add(new Y.Test.Case({
        name: 'Automated Tests',
        'should focus': function() {
            var called = false;
            var input = Y.one('#input');

            input.on('focus', function() {
                called = true;
            });

            input.focus();
            Y.Assert.isTrue(called);
        }
    }));
    Y.Test.Runner.add(suite);

This test passes normally as expected when run by opening the html file manually in a browser, but always fails when run by yeti. We suspect that yeti is stealing the focus somehow.
