Limited Availability Web components

Reference target

The referenceTarget property of a ShadowRoot object forwards attributes such as for and aria-labelledby to elements inside a shadow DOM. You can use this to, for example, link a <label> to its <input> even if the <input> is in the shadow DOM of a web component.
