iOS 17 Map sits over TabView

I'm putting together a really simple demo/learning app to try out some of the new features of iOS 17, and I've found when adding a Map to an existing TabView, the map is extending itself over the tab, which is actually still visible and can be interacted with, but is basically hidden.

There may be a modifier or something I'm missing to tell the map to stay in its frame, but I haven't found it. I have tried ones like safeAreaInsets, but that didn't seem to be right.

Here's my super-simple view:

TabView {
    Text("Not the map")
        .tabItem {
            Label("Not Map", systemImage: "person")
        }
    Map()
        .tabItem {
            Label("Map", systemImage: "map")
        }
}

And here's how it looks in the Simulator:

I will file a feedback for this, but didn't want to too quickly assume it's a bug when it's just as likely I'm not doing something right (if not more so).
