9	9	* Render callback for core/tab-list.
10	10	*
11		- * Re-renders each tab inner block with per-item context (index, id,
12		- * label) injected from the tabs-list, so the tab render callback
13		- * can add the correct IAPI directives for each button.
	11	+ * Injects IAPI directives into the saved button HTML. The buttons already
	12	+ * carry color/border/padding styles from save.jsx; this callback adds
	13	+ * tab-specific attributes (id, aria-controls, context) and interactivity
	14	+ * directives using data from the tabs-list context.
14	15	*
15		- * @since 7.0.0
	16	+ * @since 7.1.0
16	17	*
17	18	* @param array $attributes Block attributes.
18		- * @param string $content Block content (rendered inner blocks from save.js).
	19	+ * @param string $content Block content (rendered buttons from save.jsx).
19	20	* @param \WP_Block $block WP_Block instance.
20	21	*
21	22	* @return string Updated HTML.
