Layout view stuck after snackbar appears with coordinator view

I've managed to get a snackbar show successfully using a coordinator layout wrapped around a MapView in a fragment. The map view successfully slides up to allow room for the snackbar, however, once the snackbar has gone, the view stays were it is and leaves a white bar where the snackbar would appear. How can I fix this? I'm currently applying the following code as a behavior on the map view:

    @Override
    public boolean onDependentViewChanged(CoordinatorLayout parent, View child, View dependency) {
        float translationY = Math.min(0, dependency.getTranslationY() - dependency.getHeight());
        child.setTranslationY(translationY);
        return true;
    }

    @Override
    public boolean layoutDependsOn(CoordinatorLayout parent, View child, View dependency) {
        // we only want to trigger the change
        // only when the changes is from a snackbar
        return dependency instanceof Snackbar.SnackbarLayout;
    }

and my fragments view is this:

<android.support.design.widget.CoordinatorLayout
    android:id="@+id/places_coordinator_layout"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <com.google.android.gms.maps.MapView
        android:id="@+id/mapView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="com.adamshort.canieatthis.FloatingActionButtonBehaviour"/>

</android.support.design.widget.CoordinatorLayout>

I've tried searching around, but either I'm searching for the wrong thing or I no one's had a similar issue. I've seen the behavior code I have posted and working successfully in various tutorials and videos, but it doesn't behave well with the map view. Any thoughts?
