| 61 This test passes if the container's scrolling contents layer (the first child of
the GraphicsLayer with 4 children) | |
| 62 draws content only on iterations 2 and 3, and its scrolling block selection laye
r (the child of the scrolling | |
| 63 contents layer) draws content only on iteration 4. The scrolling block selection
layer should also be much smaller | |
| 64 than the scrolling contents layer. | |
