 - Steps to reproduce
/etc/config/dhcp snippet:

    config dhcp 'lan'
        option interface 'lan'
        option dhcpv6 'disabled'
        option ra 'server'
        option ra_management '1'
        list dns 'fd31:aeb1:48df::2'

Notice that "option dhcpv6 'disabled'" yet neighbour discovery is still saying DHCPv6 is available:

  $ sudo rdisc6 eth0
  Soliciting ff02::2 (ff02::2) on eth0...
  Hop limit                 :           64 (      0x40)
  Stateful address conf.    :          Yes
