Accessibility Checker already flags <abbr> elements because it natively has the underline text decoration set by at least all the browsers I’ve tested with. I’m asking if this should be flagged as a warning. I understand that putting underline to elements that aren’t links definitely warrants at least a warning, but if there’s anything I recall about <abbr> elements is that they always have a dotted underline.

If this indeed deserves a warning flag, what is the best way to style <abbr> elements that wouldn’t raise any alert from the plugin?

Thanks! In case anyone needs it, here’s what I was able to come up with for #1:

add_filter( 'render_block', function( $block_content, $block ) {
    if ( !is_admin() && ! empty( $block['attrs']['className'] ) && strpos( $block['attrs']['className'], 'user-class-here' ) !== false ) {
		$hosts = get_field('acf_user_field_id');
        if( $hosts ) {
            $hosts_list = '<p>';
            foreach( $hosts as $host ) {
                $hosts_list .= $host['display_name'];
            }
            $hosts_list .= '</p>';
            $block_content .= $hosts_list;
        }
		
    }

    return $block_content;
}, 10, 2 );

Would you be able to provide simple examples on how to use each of these?
