HTTP/2 fetch to Origin from Workers

Hi there,

Does Cloudflare Workers support http/2 fetches to an origin?

I performed the following experiment:

  • I used https://tools.keycdn.com/http2-test to test if a webhook tester, https://httpdump.io, supports http/2. It does.
  • I created a worker to send a fetch request to the endpoint I created with that service. In the playground/editor, it shows the fetch as using http1.1, and the webhook tester also reports 1.1. That’s fine, the editor has a few quirks.
  • I deployed the worker and called it outside of the editor, and it also reported http1.1

I might be imagining things but I thought http/2 had worked previously. Is this a bug or not a feature?

Thank you!
