-<p>The <strong><code>tabStop</code></strong> property of the {{domxref("Element")}} interface returns a {{jsxref("Boolean")}} indicating if the element can receive input focus via the tab key. If the specified element is a shadow host tab navigation is delegated to its children.</p>
-
-<p>This property was proposed to add tab functionality for Custom Elements. While with the existing {{domxref("HTMLOrForeignElement/tabIndex", "tabIndex")}} property, it is required to specify an order for the element to become tabbable. The <code>tabStop</code> property would decouple the tabbable property from the tab index. After feedback, this property was removed from the <a href="https://docs.google.com/document/d/1k93Ez6yNSyWQDtGjdJJqTBPmljk9l2WS3JTe5OHHB50/edit">design doc</a> and replaced by {{domxref("ShadowRoot.delegatesFocus")}}.</p>
