      Description

      Steps to Reproduce

      <image src="/image/X.png" height="100px" width="200px" onClick="self.detach()"/>
      
      1. load the zul above with iPad
        iPad 3(The New iPad), iOS 6.1.3, safari
        iPad Air, iOS 10.0.2, safari/ chrome
        iPad, iOS 5, safari
      2. click the image

      Current Result

      no effect, the image still exists

      Expected Result

      ZK invokes the onClick listener.

      Debug Info

      1. chrome device simulator can't reproduce it
      2. a button's listener works correctly. But other components without cursor:pointer have this issue, so it affects lots of components.
      3. 8.0.4.2 CE doesn't have such issue. only EE has this issue.
      4. register the touchstart event (https://developer.mozilla.org/en-US/docs/Web/Events/touchstart) instead of click event might solve this problem in an architectural way.
