SwiftUI: toolbar jump weirdly in AppleWatch

Here is the reproducible codes:

struct JumpView: View {
  
  var body: some View {
    NavigationStack {
      TabView {
        Text("Jump")
        .toolbar {
          ToolbarItem(placement: .topBarLeading) {
            Button("Done") {}
          }
        }
      }
    }
  }
}

Run directly in real apple watch device in watchOS 10.0+ (do not debug connecting with Xcode). When raise your wrist the ToolBar Button will jump weirdly.

That is odd and isn't expected, could you open a bug report and post the FB number here once you do.
