Is RFC 8441 (Websockets over HTTP2) supported by Cloudflare Workers?

I'm considering using Cloudflare Workers for an app which requires low latency websocket connections to work well (a simple TCP proxy). Are Websockets over HTTP2 supported? If it works, it would reduce my app's latency by a few hundred ms. It's not a deal breaker if this doesn't work, but I'd at least like to know this beforehand.
