      Description

      Steps to Reproduce

      Run fiddle
      http://zkfiddle.org/sample/1in4p18/5-Firefox-document-mouseUp-default

      Click in the input in sequence 1 > 2 > 1 > 2 > 1 > 2 > ....
      Note: there is a race condition between server reply and mouseUp.
      To test for this issue, keep the mouse button down without moving the mouse until after the server replies arrive and the content is selected.
      (on local / low latency, server reply will be received first)

      Current Result

      on half the clicks, the input will receive the selection, then loose selection on mouseUp because firefox will trigger caret positioning during mouseUp

      Expected Result

      Firefox should not affect selection during mouseup

      Debug Info

      Root Cause

      Firefox native document-level onMouseUp listener

      Workaround

      prevent FF default mouseUp
      deploy on zul page or globally with lang-addon

      	<script><![CDATA[
      zk.afterLoad('zul.inp', function() {
      	var xInputWidget = {};
      	zk.override(zul.inp.InputWidget.prototype, xInputWidget ,{
      		doBlur_ : function() {
      			var result = xInputWidget.doBlur_.apply(this, arguments);
      			if(zk.ff){
      				this.$n().selectionStart=0;
      				this.$n().selectionEnd=0;
      			}
      			return result;
      		}
      	});//zk.override
      });//zk.afterLoad
      ]]></script>
