setting icon to non-existing resource in iconitem will cause infinite loop in Chrome

Description

If the icon attribute is set to non-existing resource in iconitem, it will trigger onError handler to set iconNode.src to its parent's default icon which is empty string "" in this test case. Chrome will treat this empty string as resource that can not be found and will start the infite loop of triggering onError.

We need to validate the this.getParent().defaultIcon before assign it to iconNode.src in this case to prevent the infinite loop.
