Hello,
also if drag&drop is disabled on ToobarButton, Button and in each component with an image ( draggable="false" ),
the image is still draggable into an input component like Textbox or in browser addressbar.

The html generated tag for image is in the following function?
zul.LabelImageWidget
domImage_: function ()

{ var img = this._image; return img ? '<img src="' + img + '" align="absmiddle" />': ''; }

on the followiwng zul component LabelImageWidget.js file

Is there any way to override it and add the draggable="false" that maybe will stop this behavior?
