For how long? On a 7.0-R box, it works ok with a /32 prefix len:

%ifconfig
re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=9b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM>
        ether 00:0f:b5:80:53:85

        inet 208.70.104.211 netmask 0xffffff00 broadcast 255.255.255.255
        inet6 2607:f118::b6 prefixlen 64
        inet6 2607:f118::b7 prefixlen 64
        media: Ethernet autoselect (1000baseTX <full-duplex>)
        status: active

I'll try it on one of my 7.1 boxes to see if I can reproduce the OP's issue.
