Light shadow when using anonymous auth option and dark theme.

<style name="SignInTheme" parent="Theme.AppCompat">
        <item name="colorPrimary">@color/timelineBG</item>
        <item name="colorPrimaryDark">@color/timelineDark</item>
        <item name="colorAccent">@color/md_orange_500</item>

        <item name="colorControlNormal">@color/md_orange_500</item>
        <item name="colorControlActivated">@color/md_orange_A700</item>
        <item name="colorControlHighlight">@color/md_orange_A200</item>
        <item name="android:windowBackground">@color/timelineBG</item>
    </style>

As you can see the rest of the button shadows are styled corrected other than the new anonymous one.
