Automatic update from web-platform-tests compositing: Send entire scene's scroll offsets when sending WebRender display lists WebRender does not preserve spatial tree offsets when updating the spatial tree. Updating the spatial tree of a pipeline can also update the spatial tree of child pipelines. This change ensures that WebRender always gets the scroll offsets of the entire scene when modifying display lists in a way that may rebuild the spatial tree. Fixes #31807. -- wpt-commits: ac5cb53177ed51d2fe0755c84cfe38283b67b0b9 wpt-pr: 45425
