Note: the IconButton is still available, but it’s officially deprecated.
In previous versions, icon buttons relied internally on the components-icon-button. With the merger of the Button and IconButton components, WordPress removes this class name and replaces it with .components-button.has-icon.
Recommendation: Don’t rely on any internal className a component might use. If you want to target a specific component, prefer adding your own className prop and use that instead.
