Description: Adding a MaterialButton to a layout causes a ClassCastException in Android Studio, causing the entire layout to not render. We've narrowed it down to being an issue with the button elevation, since this workaround fixes the editor:

<!--  For the sake of xml preview not breaking  -->
    <style name="UnelevatedButton" parent="Widget.MaterialComponents.Button.UnelevatedButton" />

In XML:
<Button
        ...
        tools:style="@style/UnelevatedButton"
        style="@style/ActualButtonStyle"
        />
