Snackbar no longer appears when setting Opacity via App.xaml style

[jonmotos]

Describe the bug

I am attempting to set the opacity of all my snackbars to 1 (fully opaque) in order to prevent display oddities that occur when displaying snackbars over other controls (pictured, perhaps another bug?)

When setting the opacity to 1 via App.xaml Application.Resources, snackbars no longer appear at all.

To Reproduce

1. Create a SnackbarPresenter via Grid

   <Grid>
   <ContentPresenter/>
   <SnackbarPresenter/>
   </Grid>

2. Set the Snackbar style in Application.Resources

   <Application ...>
   <Application.Resources>
   <ResourceDictionary>
     <Style TargetType="ui:Snackbar">
       <Setter Property="Opacity" Value="0"/>
     </Style>
   </ResourceDictionary>
   </Application.Resources>
   </Application>

3. Set the Snackbar content via SnackbarService

Expected behavior

I would expect the opacity of the Snackbar to be 1 and the Snackbar to appear as usual.

Additional context

It appears ANY property set this way prevents a snackbar from appearing. At the end of the day, what I really want to be able to do is have a clear way to prevent the snackbar from having any transparency. I believe by default it should be opaque. I would be happy to add an example Snackbar usage to the documentation.
