🐛 waitUntil breaks their caching, cache-control ignored by cf

[dejurin]

Describe the bug

Somehow, this causes Cloudflare not to honour Cache-Control headers in Qwik. The answers do not have the cache-hit header.

Please see: QwikDev/qwik#5952 (cache-control ignored by cf)

part of code

// writing to cache
ctx.waitUntil(
    handledResponse.completion.then(() => cache.put(cacheKey, response.clone()))
);
