Coordinator Layout leaves padding on the bottom in fullscreen mode

Like a lot of other users, I'm having issues removing the bottom padding of the coordinator layout. I'm not sure if it's because the coordinator layout is implemented in the library by translation without resizing, or if I'm missing a flag.

On load:

On scroll:

My layout:

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/main_content"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:context=".activities.MainActivity">

    <android.support.design.widget.AppBarLayout
        android:id="@+id/appbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/AppTheme.AppBarOverlay">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical"
            app:layout_scrollFlags="scroll|snap">

            <android.support.v7.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                android:background="?attr/colorPrimary"
                app:popupTheme="@style/AppTheme.PopupOverlay">

            </android.support.v7.widget.Toolbar>

            <android.support.design.widget.TabLayout
                android:id="@+id/tabs"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                app:tabIndicatorHeight="0dp" />

        </LinearLayout>

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

    <com.pitchedapps.frost.views.FrostViewPager
        android:id="@+id/container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior" />

    <android.support.design.widget.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="end|bottom"
        android:layout_margin="@dimen/kau_fab_margin"
        android:visibility="gone" />

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

I have tried adding and removing fitsSystemWindows to the coordinator layout and appbar layout, but neither have helped.

The goal of this layout is to hide the status bar and nav bar, and to allow both the toolbar and tablayout to scroll out (which is why they are in a linear layout).

I have the following flags set in my main activity:

override fun onWindowFocusChanged(hasFocus: Boolean) {
    super.onWindowFocusChanged(hasFocus)
    if (hasFocus && Prefs.mainActivityLayout == MainActivityLayout.FULL_SCREEN) {
        window.decorView.systemUiVisibility = (View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                or View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                or View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                or View.SYSTEM_UI_FLAG_FULLSCREEN
                or View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY)
    }
}

The full source of this layout can be found under activity_main_hidden_tabs.xml from here. There are other variants for reference, but they do not have to be full screen.
