DNS policies don't work when DNS protocol is WARP

When the iOS client has Gateway with WARP enabled and the DNS protocol is WARP, DNS policies don’t seem to work. If I switch it to Gateway with DoH then switch back to Gateway with WARP, DNS protocol will change to HTTPS and policies work.

I’m not sure when did this occur, but I was able to repro the issue on a few different iPhones of different users, all running iOS 15.4/15.4.1 and with client version 6.10.
