### Additional Information

_No response_

Start with the ion-segment-button and ion-segment-content behavior in the Angular reproduction, focusing on how content-id connects a button to its content. Use the provided StackBlitz reproduction to confirm that the disabled second button remains interactive. Done means the disabled button is no longer interactable while the enabled button still works.
