SwiftUI：ViewThatFits结合TextField在HStack布局下无法唤起键盘

当ViewThatFits与TextField配合使用时，会出现两个异常现象：

• 本该显示HStack布局的场景下，SwiftUI仍保留VStack布局的状态
• 仅在VStack布局显示时，点击TextField才能正常唤起软键盘；切换到HStack布局后，点击TextField无法唤起键盘，控制台会输出以下错误日志：

-[RTIInputSystemClient remoteTextInputSessionWithID:performInputOperation:] perform input operation requires a valid sessionID. inputModality = Keyboard, inputOperation = , customInfoType = UIEmojiSearchOperations

复现问题的示例代码如下：

struct ContentView: View {
    @State var text1 = ""
    @State var text2 = ""

    @ViewBuilder var content: some View {
        Image(systemName: "globe")
            .font(.system(size: 100))
        Text("Hello")
            .font(.system(size: 50))
    }
    
    var textfields: some View {
        VStack {
            TextField("text1", text: $text1)
            TextField("text2", text: $text2)
        }
        .textFieldStyle(.roundedBorder)
    }
    
    var body: some View {
        ViewThatFits {
            VStack {
                content
                textfields
            }
            
            HStack {
                content
                textfields
            }
        }
        .padding()
    }
}
