Compositor-backed canvas contexts keep their transports tied to a single Compositor connection. When that connection dies, the 2D backing storage and WebGL GL objects disappear with it, but WebContent does not surface the loss to canvas contexts or create fresh host contexts after reconnect. Track compositor loss through the WebContent connection, mark WebGL contexts lost, dispatch the standard context events, and rebuild the remote proxy when the page opts into restoration. For 2D canvas, queue the canvas context loss steps, discard the dead backing storage, and create new storage before firing contextrestored.
