Single-Axis Scroll Containers: Motivation and Implementation

The provided text details a technical implementation in the Blink rendering engine that enables single-axis scroll containers, allowing an element to scroll in one direction while remaining visible or clipped in the other. This change relaxes legacy CSS constraints that previously forced both axes to become scrollable if only one was set to scroll. To support this, the engine now utilizes infinite clip rectangles to prevent unwanted clipping on the non-scrolling axis. Furthermore, the system can now split sticky positioning constraints across different ancestors, ensuring an element can "stick" horizontally to one container and vertically to another. These updates include complex modifications to paint property trees and the compositor, creating a linked chain of transform nodes to manage these independent movements. Comprehensive unit tests and a runtime feature flag ensure the new behavior aligns with evolving web standards while maintaining backward compatibility.
