[v6] `<IonFabButton>`: Label/caption / full label/caption width

Using an <IonFabButton> in ionic v6 with a label/caption results in a round button that doesn’t accommodate for the label/caption.
Can <IonButton> be used inside <IonFab> instead, which does correctly adjust to the width needed by label/caption/text inside - or does it cause subtle issues as it isn’t meant to be used as a FAB?
