Material design components button global theme overriding broken

Question

I want to simply apply styling to all buttons on a theme level like this

<style name="BaseTheme" parent="Theme.MaterialComponents.Light.NoActionBar">
     ...    
    <item name="buttonStyle">@style/DefaultButton</item>
</style>

<style name="DefaultButton" parent="Widget.MaterialComponents.Button">
    <item name="android:textColor">@color/whatever</item>
</style>

<Button
    android:id="@+id/addChannelButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom|center_horizontal"
    android:layout_margin="16dp"
    android:text="Add room" />

Why doesnt this work? It would in appcompat

// If I use Theme.MaterialComponents.Light.NoActionBar.Bridge, then it works

You should be setting materialButtonStyle instead of buttonStyle in your theme.
