            Bug ID: 275485
           Summary: [WPE][GTK] Bubblewrap sandbox should not kill
                    auxiliary process when UI process terminates
           Product: WebKit
           Version: Other
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKitGTK
          Assignee: webkit-unassigned at lists.webkit.org

                CC: bugs-noreply at webkitgtk.org

The bubblewrap sandbox should not kill auxiliary processes when the UI process terminates. Instead, let the child process terminate cleanly. The idea here is to match the behavior of unsandboxed WebKit and flatpaked WebKit and reduce the odds of bugs going unnoticed. This will allow exit handlers to run; notably, EGL termination has historically been a source of crashes. This will also avoid subverting the purpose of the watchdog thread that crashes the web process 10 seconds after the UI process exits.
