This looks to be entirely my fault. I had set up my /etc/dhcpcd.conf
with the following:

noipv6rs
interface em0
    ipv6rs
    ia_pd 0 em1/0

and had inet6 autoconf in /etc/hostname.em0.

This had worked fine for me for some time, but it seems that this
configuration causes "carrier lost" and the subsequent behavior above.

It seems that this is not a recommended configuration anyway, so I've
changed my configuration to let dhcpcd handle everything.

Replacing /etc/dhcpcd.conf with the following resolves this issue:

noipv6rs
interface em0
    ipv6rs
    ia_na 1
    ia_pd 0 em1/0

Best,
