Start with the context-switching request in the logs, then inspect client.js and remote-debugger.js around the Runtime.evaluate websocket commands. Reproduce the WEBVIEW_1 switch and subsequent element lookup, and use the reported Runtime domain error to trace the failure. Done means clicking or typing after switching webviews works without those errors.
