Why would my ViewPager go out of bound inside a CoordinatorLayout?

Question

For some reasons I can't grasp, the Viewpager in the image below overflows by the size of the menu. I'm probably not picturing something but I can't see what.

<android.support.design.widget.AppBarLayout
    android:id="@+id/appbar"
    android:layout_width="match_parent"
    android:layout_height="160dp"
    android:paddingTop="@dimen/appbar_padding_top"
    android:theme="@style/AppTheme.AppBarOverlay">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="wrap_content"
        android:layout_height="160dp"
        >
    </android.support.v7.widget.Toolbar>

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

<android.support.v4.view.ViewPager
    android:id="@+id/container"
    android:layout_width="match_parent"

    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    />

Your ViewPager goes out of bound because of the flag

app:layout_behavior="@string/appbar_scrolling_view_behavior"

that you've set in its XML layout. This us mainly used when you want to be able to use Google's Material Design scroll effects. If you're not interested in handling scrolls with the CoordinatorLayout, you can just delete that line.
