Bug Fixed: When MessageBoxButton set to YesNo Or YesNoCancel, There will be more one OK Button.

[SwaggyMacro]

As the title says.

var result = MessageBox.Show("确定删除该用户吗？", "提示", MessageBoxButton.YesNo, MessageBoxImage.Question, null, 5);
// or var result = MessageBox.Show("确定删除该用户吗？", "提示", MessageBoxButton.YesNoCancel, MessageBoxImage.Question, null, 5);
if (result != MessageBoxResult.Yes)
{
    return;
}

Then, You will get a MessgaeBox like this.

Set ok and cancel button Visibility will works.
