Can't increase size of progress circle

[yogur]

In the following code snippet, FAB increases to match parent LinearLayout. However, the FABProgressCircle dimensions are not increasing.

<LinearLayout
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:orientation="horizontal"
        android:gravity="center"
        android:padding="24dp"
        >
        <com.github.jorgecastilloprz.FABProgressCircle
            android:id="@+id/fabProgressCircle"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:arcColor="@color/colorAccent"
            app:arcWidth="4dp"
            >
        <android.support.design.widget.FloatingActionButton
            android:id="@+id/toggleStreamingButton"
            android:src="@drawable/ic_play_arrow_white_48dp"
            app:fabSize="auto"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:clickable="true"
            app:backgroundTint="@color/colorPrimary"/>
        </com.github.jorgecastilloprz.FABProgressCircle>
