Can not disable updating Last modified in Quick Edit

Hello developer,

I want to disable updating the Last modified in wp-admin/edit.php when using Quick Edit.

My code works very good when I deactive your plugin. But when I enable your plugin is not. I use Quick Edit and Inline Edit (Admin Column Pro).

I don’t want to check the Lock the Modified Date for all posts. Please help me review your plugin and update the code.

function stop_modified_date_update( $new, $old ) {
	$referer = wp_get_referer();
	if (strpos($referer, 'wp-admin/edit.php') !== false && $_SERVER['HTTP_X_REQUESTED_WITH'] === 'XMLHttpRequest') {
		$new['post_modified'] = $old['post_modified'];
		$new['post_modified_gmt'] = $old['post_modified_gmt'];
	}
	return $new;
}
add_filter( 'wp_insert_post_data', 'stop_modified_date_update', 99, 2 );

Thank you!
