/**
 * @module LinkedBlock
 * LinkedBlock components are linkable divs that yield any content nested within them. They are often used in list views such as when listing the secret engines.
 *
 * @example
 * ```js
 * <LinkedBlock
 *  @params={{array 'vault.cluster.secrets.backend.show 'my-secret-path'}}
 *  @queryParams={{hash version=1}}
 *  @class="list-item-row"
 *  data-test-list-item-link
 *  >
 * // Use any wrapped content here
 * </LinkedBlock>
 * ```
 *
 * @param {Array} params=null - These are values sent to the router's transitionTo method.  First item is route, second is the optional path.
 * @param {Object} [queryParams=null] - queryParams can be passed via this property. It needs to be an object.
 * @param {String} [linkPrefix=null] - Overwrite the params with custom route.  See KMIP.
 * @param {Boolean} [encode=false] - Encode the path.
