Library used (support-v4, appcompat-v7, ...): design
Version used: 23.2.0
Theme used: Theme.AppCompat.Light.DarkActionBar (with actionBar="false", windowNoTitle="true")
Devices/Android versions reproduced on: AVD Nexus 5 Android 6.0

Using AppBarLayout in a CoordinatorLayout with fitsSystemWindow="true", the AppBarLayout incorrectly determines its target height for collapse.

Example 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:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:context=".MainActivity">

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:minHeight="0dp"
            app:layout_scrollFlags="scroll|enterAlways|exitUntilCollapsed|snap"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />
    </android.support.design.widget.AppBarLayout>

    <android.support.v4.widget.NestedScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior">
        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="@string/lorem_ipsum"/>
    </android.support.v4.widget.NestedScrollView>
</android.support.design.widget.CoordinatorLayout>

See attached screenshots for initial appearance, and appearance after scrolling down past the point where the AppBarLayout stops collapsing further.

Problem did not occur in 23.1.1.
