There are 2 ways to solve this issue.

If scrolling is not required in the content fragment, remove app:layout_scrollFlags="scroll|enterAlways" from Toolbar (or just remove scroll, e.g. app:layout_scrollFlags="enterAlways").

If scrolling is required in the content fragment, use RecyclerView or NestedScrollView as the root layout for the fragment. The generated fragment use FrameLayout by default.

<android.support.v4.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_height="match_parent"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    tools:context=".view.WebPreviewFragment">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

    </LinearLayout>
