This sim uses default layoutBounds for ScreenView. But one of its dependencies (shred) requires non-default layoutBounds. In ShredConstants.js:
LAYOUT_BOUNDS: new Bounds2( 0, 0, 768, 464 ),
I don't know whether/how this might be affecting this sim. But other sims (e.g. build-an-atom) that use shred have been forced to use these ShredConstants.LAYOUT_BOUNDS for their ScreenViews. So it might be worth investigating why this working (or not working), etc.
