MenuItems disappear when using FSV in a fragment

FSV is the centerpiece of my application, mostly due to the way it handles icons beautifully. However, once I moved FSV into a fragment, instead of an activity, the icons stopped showing up as in the demo, and started showing up like regular android menus.

This is what it looks like with the menu from the sample:

Here's the widget as defined in my Fragment's XML:

    <com.mypopsy.widget.FloatingSearchView
        android:id="@+id/uiSearch"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginLeft="35dp"
        android:layout_marginRight="35dp"
        android:layout_marginTop="150dp"
        android:background="#90000000"
        android:hint="@string/search"
        android:translationZ="12dp"
        app:fsv_contentBackgroundColor="@color/white"
        app:fsv_cornerRadius="5dp"
        app:fsv_menu="@menu/search"
        tools:context=".MainActivity"/>

The menu items work when clicked on. The MenuProgressBar class doesn't show at all.

This may be a theming issue or unrelated to fragments. I'm not exactly sure.

I don't think it's relevant info, but I'm using Kotlin and Android Studio 3.

After some time, I figured out FSV is just not compatible with all activities. It IS compatible with AppCompatActivity, but not with FragmentActivity.
