DNS queries over quic are slow

[sylr]

All my DNS queries over quic are taking no less than 2s:

$ doggo app.discord.com @quic://dns.adguard.com --time
NAME            	TYPE	CLASS	TTL 	ADDRESS        	NAMESERVER         	TIME TAKEN
app.discord.com.	A   	IN   	295s	162.159.135.232	dns.adguard.com:853	2615ms

app.discord.com.	A   	IN   	295s	162.159.137.232	dns.adguard.com:853	2615ms

It seems related to doggo, using another client works normally:

$ time dnslookup abstraction.fr quic://dns.adguard.com
dnslookup master
Server: quic://dns.adguard.com

dnslookup result (elapsed 85.917167ms):
