* @typedef ButtonProps
* @prop {string} [buttonText] -
* The presence of this property indicates that the button will have a visibly-rendered
* label (with this prop's value). For brevity, when providing `buttonText`, the `title`
* prop is optional—if `title` is not present, the value of `buttonText` will be used for
* the button's `title` attribute, as they are typically identical. When this prop is
* missing, an icon-only button will be rendered.
* @prop {string} [className] -
* When present, this will be used as the base class name and will override all styling.
* See `buttons` SCSS mixins module for more details.
* @prop {string} [icon] -
* The name of the SVGIcon to render. This is optional if a `buttonText` is provided.
* @prop {'left'|'right'} [iconPosition] - Whether icon should render to the left or
* to the right of label text
* @prop {boolean} [isExpanded] -
* Is the expandable element controlled by this button currently expanded?
* @prop {boolean} [isPressed] -
* Indicate that this is a toggle button (if `isPressed` is a boolean) and whether it
* is pressed. If omitted, the button is a non-toggle button.
* @prop {(e: Event) => any} [onClick] - callback for button clicks
* @prop {boolean} [disabled] - disables the button when true
* @prop {Object} [style] - optional inline styling
* @prop {string} [title] -
* `title`, used for button `title`, is required unless `buttonText` is present
