I do not have any other interfaces in /etc/network/interfaces, besides lo.
Thanks for the tip about systemctl -l status network-manager. There is a
difference.
I ran systemctl -l status network-manager on two boots. In both cases, the USB
dongle was already plugged in and was not touched. The first boot, I logged
into Mate, and the wifi connected automatically:

...
Now the boot where network-manager repeatedly asked for the same password:
