Version 2.5.2 of our Perfmatters plugin is live!

Please, please don't use `font-display: swap` with icon fonts. I mean, as a rule, don't use icon fonts — SVGs are so much better — but if you must, then don't use `swap`. It doesn't make sense to see random fallback letters for icons.
Do me a favour and check your site now if using icon fonts.
