Lighthouse is not recognizing display=wap from google fonts. Apparently the url is being generated with errors in Joomla 4 it looks double & instead of & or &
code:
<link href="//fonts.googleapis.com/css?family=Roboto:100,100i,300,300i,400,400i,500,500i,700,700i,900,900i&subset=latin&display=swap" rel="stylesheet" media="none" onload="media="all"" />
Tested in Joomla 4 and Helix ultimate 2.0.4, PHP 7.4.20
