     * glyph. wp-admin loads dashicons for the outer document as part of the
     * concatenated load-styles.php admin bundle, which the canvas does not inherit,
     * so a selected dashicon rendered as a 0x0 span with no glyph. Font Awesome was
     * unaffected because it is a plugin stylesheet that does reach the canvas.
     *
     * The front end enqueues dashicons from the accordion block's render_callback in
     * blocks/accordion.php, so it is only needed here for the editor.
