AI review CONFIRMED
Classified as not security-relevant. overscroll-area negative-scroll layout feature (not a security fix).
Triage note: Adds `scrolls_all_directions_` handling in `ScrollableOverflowCalculator` so overscroll-area pseudo-elements can scroll to negative offsets, plus WPT/unit tests. A CSS *scroll*-overflow behavior feature; 'overflow' here is scrollable-overflow, not integer/buffer overflow. Structural false positive.
