[BUG Report] ‘reference’ shortcode

This issue still not fixed after 5 months 🙁

The code below is having a huge impact on the site’s performance!

It filters all content of all post types and do all shortcodes to that contents (easydocs/shortcodes/reference.php)

add_filter( 'the_content', function ( $ezd_content ) {
	$ezd_options      = get_option( 'eazydocs_settings' );
	$is_notes_title   = $ezd_options['is_footnotes_heading'] ?? '1';
	$notes_title_text = $ezd_options['footnotes_heading_text'] ?? __( 'Footnotes', 'eazydocs' );
	$footnotes_column = $ezd_options['footnotes_column'] ?? '1';

	$all_shortcodes = ezd_all_shortcodes( $ezd_content );
	$all_shortcoded = '';
	foreach ( $all_shortcodes as $all_shortcode ) {
		$all_shortcoded .= '<span>' . do_shortcode( $all_shortcode[0] ) . '</span>';
	}

	$ezd_footnote_title = '';
	if ( ! empty( $notes_title_text ) && $is_notes_title == '1' && has_shortcode( $ezd_content, 'reference' ) ) {
		$ezd_footnote_title = sprintf( '<div class="ezd-footnote-title">%s</div>', $notes_title_text );
	}

	$footnotes_contents = '';
	if ( has_shortcode( $ezd_content, 'reference' ) ) {
		$footnotes_contents = $ezd_footnote_title . "<div ezd-data-column='" . $footnotes_column . "' class='ezd-footnote-footer'>" . $all_shortcoded
		                      . "</div>";
	}

	return $ezd_content . $footnotes_contents;
} );

You should apply this filter to certain post types ONLY

And ONLY when the content has ‘reference’ shortcode

Or at least provide a function name so we can remove the filter.

function ezd_reference_content_filter($content) {
    $types = apply_filters('ezd_xxxx', ['doc']);
    if ( !in_array( get_post_type(), $types ) || !has_shortcode( $content, 'reference' ) ) {
        return $content;
    }
    xxxxxx
    xxxxxx
    return $content;
}
add_filter( 'the_content', 'ezd_reference_content_filter' );

Thanks in advance
