Visual viewport scroll and pinch zoom used to invalidate the full accumulated visual context tree and display list, even though those changes only modify the root visual viewport transform. That forced a full display list rerecord before sending updated compositor state. Patch the reserved visual viewport AVC node in place instead. VisualViewport marks the tree for compositor update without invalidating the display list, and Navigable sends the replacement tree through the new IPC path before updating scroll state.
