Bug when using zoomIn function on 2D mode


I've encountered a bug.

by using the following code:
    @import url(../templates/bucket.css);
<div id="cesiumContainer" class="fullSize">
<button type="button" id="zoomIn" onclick="zoomIn()"></div>
<div id="loadingOverlay"><h1>Loading...</h1></div>

var viewer;
require(['Cesium'], function(Cesium) {
    "use strict";

    viewer = new Cesium.Viewer('cesiumContainer');

    function zoomIn(){

after zooming few times the program stopped working and gave me the next error:

An error occurred while rendering. Rendering has stopped.
DeveloperError: right must be greater than left.

    at render (http://cesiumjs.org/Cesium/Source/Widgets/Viewer/Viewer.js:69:28)

I tried the code on the demos in the site, and also in my program, the example is an edited code i made on the cesium viewer widget demo in the sandcastle in your site.

Are you familiar with that bug?

Thanks for the help,

Hi Gilad,

This has been fixed in master (#1437) and will be in the next release.
