如何防止TextBox在Uno平台失去焦点后隐藏在安卓系统中的软键盘？

using Uno.UI.Xaml.Input;
using Windows.UI.Xaml.Controls;

// ...

TextBox textBox = new TextBox();

// 订阅Showing和Hiding事件
InputPaneHelper.Instance.Showing += InputPaneHelper_Showing;
InputPaneHelper.Instance.Hiding += InputPaneHelper_Hiding;

// Showing事件处理程序
private void InputPaneHelper_Showing(object sender, InputPaneHelperEventArgs e)
{
    // 将TextBox的底部边距设置为软键盘的高度
    textBox.Margin = new Thickness(0, 0, 0, e.OccludedRect.Height);
}

// Hiding事件处理程序
private void InputPaneHelper_Hiding(object sender, InputPaneHelperEventArgs e)
{
    // 将TextBox的底部边距重置为0
    textBox.Margin = new Thickness(0);
}
