autoptimize_fitler_css_preload_and_print bug?

I’m trying to revert to the old way of deferring CSS to work with a javascript I had written long ago to further delay the CSS from loading but this is leading to some weird output that looks like a bug because there are two link tags being output (excluding the one inside the noscript tag)

My filters

add_filter('autoptimize_filter_css_preload_onload', function() {
	return "this.onload=null;this.setAttribute('data-loaded', '1');";
}, 10, 0);

add_filter('autoptimize_fitler_css_preload_and_print', '__return_true');
