Could you look into why the test is failing?

            var store;
            var map;
            var layer;
            beforeEach(function() {
                layer = new ol.layer.Vector();
                var layer2 = new ol.layer.Vector();
                map = new ol.Map({
                    layers: [layer, layer2]
                });
                store = Ext.create('GeoExt.data.store.Layers', {map: map});
            });

            it('unbinds events on destroy store', function() {
                store.destroy();
                expect(store.map).to.be(null);
                // exemplary check "remove" event to ensure the events are
                // unregistered
                expect(function() {
                    map.removeLayer(layer);
                }).not.to.throwException();
                // map layers remain untouched
                expect(map.getLayers().getLength()).to.be(1);
                // store is empty now
                expect(store.getCount()).to.be(0);
            });

This is the test that fails in both browsers. Unexpectedly map.removeLayer(layer); throws an exception, and map.getLayers().getLength() is 2 not as in the test expected 1.

Hmm. My expectation would be that map.getLayers().getLength() is a follow up error, since the removal hasn't worked. The test itself though is a bit pointless.

Nice find, friends.
