| 54 A non-composited fixed-position element can get grouped into a composited
container. | |
| 55 In this case, repaint invalidations were incorrectly going to the LayoutV
iew instead | |
| 56 of the composited container. The incorrect result was that the fixed-pos
ition element | |
| 57 never repainted, and it appeared to scroll along with the composited cont
ainer. | |
