[BUG] miniflare aggressively buffers responses

[vicb]

There is a bug in [email protected] causing responses to be aggressively buffered.

It breaks PPR in Next.js with wrangler dev - PPR works fine when deployed.
See opennextjs/opennextjs-cloudflare#309

I have a pretty good idea of the the root cause and how to fix that.
I'll add more details here later this week and will submit a fix PR.

One workaround for now is to set the Content-Encoding of the response to identity (any value other than gzip or br should do).

/cc @mhart @jasnell as we discussed it earlier

I reported something similar a long time ago. Is this a same issue? #6577

[vicb]

@hi-ogawa this is probably the same root cause - I'll work on that probably early next week. Let's keep both issues opened until then.

Thanks!
