I can see validCORSHeaders() at xmlhttprequest.js doesn't support Access-Control-Max-Age.
We can follow https://www.w3.org/TR/cors/#access-control-max-age-response-header to cache the preflight request result.

That spec is outdated; we want to use https://fetch.spec.whatwg.org/ instead. But yeah, seems like a reasonable feature.
