WPF Material Design Textbox is showing through slides. Is there a workaround?

Question

I tried using a textbox inside a WPF Material Design transitioner slide. The textbox is visible even when changing slides.

A dotted line from the textbox on the next slide is visible, and viceversa.

Has anyone else encountered this issue? Is there any workaround I could use?

This is the xaml I used. I am using the transitioner control although I believe the flipper control causes a similar effect when used with textboxes.

<Grid>
    <materialDesign:Transitioner SelectedIndex="0">
        <materialDesign:TransitionerSlide>
            <StackPanel HorizontalAlignment="Center">
                <TextBlock Text="Hello, this is my first page!" Margin="10"/>
                <TextBox materialDesign:HintAssist.Hint="Type your first text here!" Margin="10"/>
                <Button Command="{x:Static materialDesign:Transitioner.MoveNextCommand}" Content=">" HorizontalAlignment="Center" Margin="10"/>
            </StackPanel>
        </materialDesign:TransitionerSlide>
        <materialDesign:TransitionerSlide>
            <StackPanel HorizontalAlignment="Center">
                <TextBlock Text="Hello, this is my 2nd page!" Margin="15"/>
                <TextBox materialDesign:HintAssist.Hint="Type your second text here!" Margin="15"/>
                <Button Command="{x:Static materialDesign:Transitioner.MovePreviousCommand}" Content="&lt;" HorizontalAlignment="Center" Margin="15"/>
            </StackPanel>
        </materialDesign:TransitionerSlide>
    </materialDesign:Transitioner>
</Grid>

I believe the issue might lie in the dotted line that appears when a textbox is disabled, so possibly by removing that, the textbox would no longer show through slides. But that's just my guess.

Any help is appreciated!

For the best approach, please refer to this answer.

Try to add the following implicit style to your App.xaml or window:

<Style TargetType="materialDesign:BottomDashedLineAdorner">
    <Setter Property="Visibility" Value="Collapsed" />
</Style>
