Style based on MaterialDesignOutlinedTextBox can't set Padding

Bug explanation

I want to use a Style for TextBox based on MaterialDesignOutlinedTextBox and set the Padding.
This doesnt work.

What I did:

• create a TextBox Style (implicit or with a x:Key) based on MaterialDesignOutlinedTextBox
• have a Setter for Padding
• create a TextBox deriving from it

<!--in the Resources -->
<Style x:Key="SampleStyle" TargetType="{x:Type TextBox}" BasedOn="{StaticResource MaterialDesignOutlinedTextBox}">
     <Setter Property="Padding" Value="5"></Setter>
</Style>


<!--in Body of the UserControl / Page / Window-->
<TextBox Style="{StaticResource SampleStyle}" Text="Sample"/>

Result:
No Padding changes

Expected:
Padding changes

When I change the Padding at the TextBox directly

<TextBox Padding="5" Style="{StaticResource SampleStyle}" Text="Sample"/>

The Padding changes

The Project is in WPF with .net6.0-windows

Version

4.5.0

Reproduce the issue with the provided WPF .NET 6 XAML and inspect the MaterialDesignOutlinedTextBox style and its control template. Verify how Padding is applied through a derived Style versus directly on the TextBox; done means the Style setter changes Padding while direct Padding behavior remains intact.
