This looks like it is referring to a type: 'settings-passwords-and-forms-page'
Should it be this instead? 'autofill-category'

Add @type for the Object.
For simple properties like String and Boolean the @type is not needed.
But for Object and Array, add an @type (or @private).

Does this need to be an array: [this.checked]?
