I see the page is not refreshed and packets are still being sent. It might be that the process is killed (memory maybe) or suspended for long enough that the connection gets disconnected. 1987093 3 youennf 2023-10-24 01:55:57 -0700 We would probably need a sysdiagnose since I cannot reproduce. It is not unexpected that a page got disconnected since the process might be suspended if the user is in a phone call. Please reopen if you can still reproduce and can provide a sysdiagnose.
