Snackbar flickers if android:animateLayoutChanges is true on root layout

Question

It seems like a simple Snackbar message looks pretty jarring if android:animateLayoutChanges is set to true. The Snackbar will flicker repeatedly throughout the animation. Removing the android:animateLayoutChanges parameter from the layout solves this issue but now I won't get to enjoy the benefits from it. It also works if I use android:animateLayoutChanges on a child view instead of the root view.

Is this a known issue and is there a way around it?

Here is an example layout which will demonstrate the issue if a snackbar is shown.

<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.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:animateLayoutChanges="true">

    <com.google.android.material.bottomappbar.BottomAppBar
        android:id="@+id/bottomAppBar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom"
        app:backgroundTint="@color/colorPrimary"
        app:fabAlignmentMode="end"
        app:fabCradleMargin="4dp"
        app:fabCradleRoundedCornerRadius="16dp"
        app:fabCradleVerticalOffset="4dp"
        app:popupTheme="@style/ThemeOverlay.MaterialComponents.Light"
        app:theme="@style/ThemeOverlay.MaterialComponents.Dark.ActionBar" />

    <com.google.android.material.floatingactionbutton.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:backgroundTint="@color/colorAccent"
        app:layout_anchor="@id/bottomAppBar"
        app:srcCompat="@drawable/ic_add"
        app:tint="@color/colorWhite" />

</androidx.coordinatorlayout.widget.CoordinatorLayout>
