It's not a ("simple") bug, but a general problem with peers with
multiple addresses – wireguard only stores one in the kernel, it doesn't
do multipath, by design.

Thus the frontend needs to remember all addresses, send one to the
driver, wait a bit, check whether a link could be established, then try
with another peer address. Repeat until success. Bonus points for
repeating the host name lookup.
