White inactive bottom space on CoordinatorLayout

Question

I have the xml-file with CoordinatorLayout

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:visibility="visible"
    android:gravity="center_horizontal">
            <android.support.design.widget.CoordinatorLayout
                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="wrap_content">
                <android.support.design.widget.AppBarLayout
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
                    android:layout_marginStart="4dp"
                    android:layout_marginEnd="4dp"
                    android:layout_marginLeft="4dp"
                    android:layout_marginRight="4dp">
                    <android.support.design.widget.TabLayout
                        android:id="@+id/tabLayout"
                        app:tabBackground="@drawable/my_tab_item_bg_selector"
                        app:tabMaxWidth="0dp"
                        app:tabGravity="fill"
                        app:tabMode="fixed"
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content" />
                </android.support.design.widget.AppBarLayout>
                <android.support.v4.view.ViewPager
                    android:id="@+id/viewPager"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    app:layout_behavior="@string/appbar_scrolling_view_behavior"/>
            </android.support.design.widget.CoordinatorLayout>
</LinearLayout>  

And I have another xml-file which I put on coordinator layout

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.NestedScrollView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/nestedScrollData"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:layout_behavior="@string/appbar_scrolling_view_behavior">
    <LinearLayout
        android:id="@+id/layoutDataDispatchContacts"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:gravity="center_horizontal">

        <LinearLayout
            android:id="@+id/layoutFullTableDispatchContacts"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical"
            android:gravity="center_horizontal"
            android:background="@drawable/layout_block_background">
            <LinearLayout
                android:id="@+id/tableLinearLayoutDispatchContacts"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:orientation="vertical"
                android:gravity="center_horizontal">
            </LinearLayout>
        </LinearLayout>
    </LinearLayout>
</android.support.v4.widget.NestedScrollView>

I catching bug of empty space, which covers the part of my window and not clickable. This is on screenshot below: unclickable inactive bottom space I noticed that when I deleting app:layout_behavior="@string/appbar_scrolling_view_behavior" from my ViewPager, the bug disappears. But my names of tabs disappear too. I think it creates some invisible toolbar or something like that.

As CoordinatorLayout is working as parent of subviews so, to occupy full screen you need to set the height to match parent instead of wrap_content like this:

android:layout_height="match_parent"

and it would work fine.
