| 58 This test passes if the container's scrolling contents layer (the first child of
the GraphicsLayer with 4 children) |
| 59 doesn't draw content at all, and its scrolling block selection layer (the child
of the scrolling contents layer) |
| 60 draws content only on iteration 2. The scrolling block selection layer should al
so be much smaller than the |
| 61 scrolling contents layer. |
