 * `<vaadin-master-detail-layout>` is a web component for building UIs with a master

 * The following state attributes are available for styling:
 *
 * Attribute      | Description
 * ---------------| -----------
 * `containment`  | Set to `layout` or `viewport` depending on the containment.
 * `orientation`  | Set to `horizontal` or `vertical` depending on the orientation.
 * `has-detail`   | Set when the detail content is provided.
 * `drawer`       | Set when the layout is using the drawer mode.
