--- Comment #19 from gordon lee <hi0912 at qq.com> ---
I got the same problem when use hocuspocus/provider for collaboration edit docs which use websocket(https://github.com/websockets/ws) in iOS15.0 or iOS16.4.1 webview

those step can reproduce this bugs:
1. First open wifi & cellular;
2. Open my share collaboration edit that will use wifi priority connect to remote Websocket server;
3. Turn off the wifi; even the client close websocket by call ws.close() the websocket has no fire close event that caused the connection hang forever util  lock screen;

its most important for those apps which use WKWebView to ingest collaboration apps.
