Rotate the globe and you'll see that this is supposed to be a full corridor that gets clipped at the left edge of the globe in the picture above.

If you replace line 25:

```
geometry: new Cesium.CorridorGeometry( ovalDesc ),
```

with:

```
geometry: circleGeom,
```

You'll see that a large circle gets rendered fine without clipping.

Reproduce the clipped corridor from the linked Sandcastle example and compare line 25 using CorridorGeometry with the circleGeom alternative. Rotate the globe to confirm the corridor is clipped at the globe edge, then trace CorridorGeometry's rendering and clipping behavior. Done means the full large corridor renders without the reported edge clipping while the circle comparison remains correct.
