Firefox在预加载字体上显示警告，尽管它们在第一秒内就被使用了

我们使用以下代码在本地预加载（出于pagespeed原因）Google字体：

<link rel="preload" href="/css/google-fonts/6xK3dSBYKcSV-LCoeQqfX1RYOo3qOK7l.woff2" as="font" crossorigin>
<style type="text/css" media="screen, print">
    @font-face {
    font-family: 'Source Sans Pro';
    font-display: swap;
    font-style: normal;
    font-weight: 400;
    src: local('Source Sans Pro Regular'), local('SourceSansPro-Regular'), url(/css/google-fonts/6xK3dSBYKcSV-LCoeQqfX1RYOo3qOK7l.woff2) format('woff2');
    unicode-range: U+0000-00FF, U+0131, U+0152-0153, U+02BB-02BC, U+02C6, U+02DA, U+02DC, U+2000-206F, U+2074, U+20AC, U+2122, U+2191, U+2193, U+2212, U+2215, U+FEFF, U+FFFD;
    }
</style>

Deepl Translation的内容如下：

The resource at "http://localhost:8080/css/google-fonts/6xK3dSBYKcSV-LCoeQqfX1RYOo3qOK7l.woff2" was preloaded ("link-preload") but not used within the first seconds. It is recommended to check if all preload attributes are set correctly.

我已经检查了stackoverflow并发现：

现在我想知道在Firefox86中使用它时，它是否应该已经起作用了（支持从FF85开始描述）

我有什么遗漏吗

The resource at "http://localhost:8080/css/google-fonts/6xK3dSBYKcSV-LCoeQqfX1RYOo3qOK7l.woff2" was preloaded ("link-preload") but not used within the first seconds. It is recommended to check if all preload attributes are set correctly.
