ipv6 SLAAC gateway not cleared during disconnect

I'm using ipv6 stateless address autoconfiguration (SLAAC) with connman, currently version 0.64 daily builds. When I reboot my wifi ap running radvd and random link local address (presumarably due to the bridge interface in ap) my laptop disconnects and when I have to connect again. But after I have reconnected ipv6 doesn't work anymore.

I investigated the issue and found out that I have actually two ipv6 default routes at that point. First one is the old non-existent address and the second one is the new link local address of the ap. If I remove the first route, ipv6 works again.
