staleConnectionTimeout does not work

[yuanmai]

version: 0.4.14

I created a server using WebServers.createWebServer. I could send & receive messages, when I closed the Chrome tab (websocket client), the WebSocketHandler.onClose method was triggered. But if I disconnect the network of the ws client, it won't trigger the onClose method, or it would take a few minutes to trigger it. According to the source code, the default value of staleConnectionTimeout should be 5 seconds.

I'm having the same issue currently with 0.4.14. Setting the staleConnectionTimeout (or just leaving it at the default of 5 seconds) seems to have no effect.

If I leave a connection open and send no data across the wire, it never closes itself
If I disconnect my network connection from the client, the server never cleans up the WebSocketConnection

What is the expected behavior here?
