entity selecting when viewer.scene3DOnly = true

[anne-gropler]

Minimum code to reproduce this in Sandcastle:

var viewer = new Cesium.Viewer('cesiumContainer', {scene3DOnly:true});

viewer.camera.setView({
    destination :Cesium. Cartesian3.fromDegrees(13.305, 52.528, 3000)
});

viewer.entities.add({
    position: Cesium.Cartesian3.fromDegrees(13.305, 52.528, 3000),
    cylinder : {
    length : 400.0,
    topRadius : 0.0,
    bottomRadius : 200.0
    }
});

Scroll out to see the cone. Click on it to select it. The green brackets should follow the cone, but they don't.
Double-click to track it. You will see the green brackets, the rest is black. Click the home button to untrack it and it will throws:

This does not happen with scene3DOnly: false.
This does not happen when you add an Ellipse instead of a cylinder.
And this does not happen when you add 2 entities. Just with one.
Strange: Adding one cylinder from within in the viewer (call it A), and others from within a viewerMixin (call it B), this happens with BOTH. So add one in A: bug, and add one in B: bug, although there are 2 entities now in the same entitiesCollection. Add one more in A: bug fixed for A's entities, but not for B's entity.

Thanks for the very detailed description @anne-gropler! This is definitely a strange bug. We'll try take a look at it soon!
