iOS 26 tabViewBottomAccessory doesn't work with tabViewSidebarBottomBar

The code is shown as follows. Once the tabViewBottomAccessory is enabled, the tabViewSidebarBottomBar disappears.

        TabView {
            Text("tab a")
                .tabItem {
                    Image(systemName: "a.square")
                    Text("Tab A")
                }
                .ignoresSafeArea(edges: [.all])
            
            
            Text("tab b")
                .tabItem {
                    Image(systemName: "b.square")
                    Text("Tab B")
                }
                .ignoresSafeArea(edges: [.all])
        }
        //.tabViewBottomAccessory {
        //    Text("tabViewBottomAccessory")
        //}
        .tabBarMinimizeBehavior(.onScrollDown)
        .tabViewStyle(.sidebarAdaptable)
        .tabViewSidebarBottomBar {
            Text("tabViewSidebarBottomBar")
        }
