Description msiddiqu 2020-09-22 20:39:06 UTC 
When recursing through graphical layers while scrolling, an iterator may have become invalid, resulting in a potential use-after-free. This occurs because the function `APZCTreeManager::ComputeClippedCompositionBounds` did not follow iterator invalidation rules.
