WebDriver BiDi clients identify DOM nodes by a `script.SharedId`. `script.evaluate` and `script.callFunction` return a node as a `NodeRemoteValue` with a `sharedId`, and the client passes it back as a `script.SharedReference`. That can go to `script.callFunction`, or serve as the element for `input.performActions` origins, `input.setFiles`, `browsingContext.captureScreenshot` clips or `browsingContext.locateNodes`.
