DialogHost background fade out is to slow when using MaterialDesignEmbeddedDialogHost and TransitionAssist.DisableTransitions="True"

[poralcode]

I'd like to disable the transition of the DialogHost and at the same time, use the style MaterialDesignEmbeddedDialogHost.

<md:DialogHost
                Grid.Row="1"
                md:TransitionAssist.DisableTransitions="True"
                Identifier="ContainerDialogHost"
                SnackbarMessageQueue="{Binding ElementName=MySnackbar, Path=MessageQueue}"
                Style="{StaticResource MaterialDesignEmbeddedDialogHost}">

</md:DialogHost>

Together with md:TransitionAssist.DisableTransitions="True" and MaterialDesignEmbeddedDialogHost , opening the dialog is faster. However, upon closing it, I noticed that the Background is slowly fading out. Are there any other settings I am missing? There also should be no animation whatsoever upon closing it.
