Pull request overview

Updates WordPress’s KSES HTML allowlist to permit the autofocus attribute only on the <dialog> element (per Trac #65491), and adds a PHPUnit regression test to ensure autofocus is preserved on dialogs but stripped from other elements in post content.

Changes:

• Allow autofocus on <dialog> in the default post-content KSES allowlist.
• Add a PHPUnit test asserting autofocus is kept for <dialog> and removed for other focusable elements in wp_kses_post().
