hi
I create a custom control for SemanticZoom. Demo is as follow:
html:
<div id="sezoDiv" data-win-control="WinJS.UI.SemanticZoom" style="height: 1000px">
<div id="ZoomedInDiv" data-win-control="CustomControls.CustomControl">
<div>.....</div>
<div>.....</div>
</div>
<div id="ZoomedOutDiv" data-win-control="CustomControls1.CustomControl">
<div style="background: #f00; width: 100px; height: 100px"></div>
</div>
</div>
.....


When content is overflowed , the scroll bar appear 。But the right orange range is not shown。When I use the mouse to slide the range , it's may be shown.
What reason is this, how to solve
