Does ESNI not work?

I set Cloudflare(DOH) as resolver and enabled network.security.esni.enabled via about:config on my Firefox. When I check it here, https://www.cloudflare.com/ssl/encrypted-sni/
Everything except ESNI gets a green tick mark.
It works only if I set network.trr.mode to 2 or 3 but in that case Firefox doesn't use dnsproxy. It uses the default uri of Firefox which is https://mozilla.cloudflare-dns.com/dns-query. This is cloudflare too but it's not the resolver I set on SimpleDNSCrypt so I don't get any logs.
