/**
 * PR by Sybre Waaijer:
 * @link https://github.com/ahmedkaludi/accelerated-mobile-pages/pull/761
 *
 * @since version 0.9.48 :
 *   1. Removes unused code.
 *   2. Cleaned up code.
 *   3. Keeps legacy action in place.
 *   4. No longer replaces the title tag.
 *   5. Instead, filters the title tag.
 *   6. Therefore, it works with all SEO plugins.
 *   7. Removed direct Yoast SEO compat -- It's no longer needed.
 *   8. Removed unwanted spaces.
 *   9. Improved performance.
 *   10. Improved security.
 *   11. Added support for CPT and attachment pages.
