---------------------------------------------
强行通过 ITextInputConsumer 开启 ContentDialog 的输入后，普通的文本框输入存在问题
After the ContentDialog input of Xaml islands is enabled through ITextInputConsuonsumer and ITextInputProducer, the input performance of ContentDialog is normal. The TextBox of a normal window, however, repeats the input when entering characters.The application being tested uses a Window created by FrameworkView and adds controls to Window.current to display it.
