Wire desktop app session remains active in background after closing, but user is prompted with login screen when app icon is clicked

[intp56]

I'm experiencing a problem on Wire Desktop version 3.39.3653 for (Ubuntu-based) Linux, which seems very much related to this closed issue: #851 . The app is presenting the log-on screen after the app has been "closed", despite the session current remaining active. The app gives no appearance of remaining open, but incoming calls and messages still get through, presenting the app in normal signed-in state when responded to, until the app is manually "closed" again (obviously the current session remains running silently in the background) until the app icon is clicked, whereupon the user is presented with a sign-in screen instead of taking you to the the existing session as it should. Is this a known issue?
