TabView on iPad, problems with tabbar

SwiftUI's TabView seems to have problems when being used in a sidebar on iPad. This example works completely fine on iPhone, only iPad makes problems:

NavigationView{
            TabView{
                Text("Test 1").tabItem{
                    Image(systemName: "folder")
                }
                Text("Test 2").tabItem{
                    Image(systemName: "tag")
                }
                Text("Test 3").tabItem{
                    Image(systemName: "star")
                }
            }
        }

The tabbar width is not calculated correctly and as a result not all buttons are shown. In the screenshot there should be three buttons visible, but only 2 are shown, "folder" is missing:

Has someone a solution or workaround for this? I have tested this with iOS 17 and 17.2.
