我已经禁用了HTTP2并稍微修改了serviceWorker.js文件，它已经平了一点，但每隔一段时间我们仍会连续看到5-15个请求，就像今天一样：

对serviceWorker.js的请求的返回标头是：

serviceWorker.js的当前内容：
self.addEventListener('fetch', function() {
return;
})
我们如何注册：
if ('serviceWorker' in navigator) {
window.addEventListener('load', function() {
navigator.serviceWorker.register('/serviceWorker.js', {
scope: '/mobile'
}).catch((error) => {
// eslint-disable-next-line no-console
console.log("Service worker registration failed: ", error);
});
});
}
为什么会发生这种情况？并且只有最新的Safari？
