PasswordBox placeholder text isn't returning when cleared

Question

So I have a PasswordBox:

<PasswordBox x:Name="pwbPassword" PlaceholderText="Password" 
             Password="{x:Bind Path=local:Password, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"/>

However I also have a clear function which contains:

Password = null

The issue I am having is that the PlaceholderText isn't being reinstated and instead the box is left blank.

Is this a bug or am I missing somthing?

PasswordBox placeholder text isn't returning when cleared

I check your code, Password is string property, please bind with string field.

<PasswordBox

    Name="MyPassswordBox"
    Height="44"
    MaxLength="20"
    Password="{x:Bind PassWord, Mode=TwoWay}"
    PlaceholderText="Input your Password"
    />

Code behind

private string _passWord;

 public event PropertyChangedEventHandler PropertyChanged;
 private void OnPropertyChanged([CallerMemberName] string propertyName = null)
 {
     if (PropertyChanged != null)
     {
         this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
     }
 }
 public string PassWord
 {

     get { return _passWord; }
     set
     {
         _passWord = value;
         OnPropertyChanged();

     }
 }

If you want clear password, please set PassWord as null.

private void Button_Click(object sender, RoutedEventArgs e)
{
    PassWord = null;
}

I have tested, the PlaceholderText will be reinstated.
