+Subject: [PATCH] Fix crash when connecting a new screen
+
+In QWaylandWindow::virtualSiblings, don't include screens that have not been
+added yet. I.e. QWaylandScreens for which QPlatformIntegration::screenAdded has
+not yet been called.
+
+There are two reasons why this crash wasn't covered by the
+removePrimaryScreen() test. First of all, the mock output didn't send
+wl_output.done events when updating the mode/geometry. These wayland events are
+what causes QWindowSystemInterface::handleScreenGeometryChange() to be called
+(where virtualSiblings are called).
+
+Furthermore, virtualSiblings is only called when the geometry actually changes,
+so add a new test that changes the screen geometry of the existing screen while
+a new one is being added (i.e. moves it to the right).
+
