Root Cause

the iframe is nested into a separate div
at the same time the iframe doesn't get any additional styles to cover the div accordingly

<div id="qMiZ1" style="width: 100%; height: 100%; overflow: auto;" class="z-iframe" src="" frameborder="0">
  <iframe id="qMiZ1-real" frameborder="0" style="-webkit-overflow-scrolling: touch; overflow: auto;" 
          src="test.zul" z_xsrc="http://localhost:8080/test.zul" ...></iframe>
</div>

add a style to cover 100% of the div

	.ios .z-iframe iframe {
		width: 100%;
		height: 100%;
	}
