AFAIK this is expected behavior: interfaces managed outside
NetworkManager (e.g. in /etc/network/interfaces) are ignored and
considered up (but nothing else is done); unless the value of the key
"managed" (under [ifupdown]) is set to true in
/etc/NetworkManager/NetworkManager.conf. Its value defaults to false.
Now whether that works well with dnsmasq is an entirely different
matter, but if there are issues with that it should be filed as a
separate bug.
Since it's "fixed" in all supported Ubuntu releases (this behavior
predates dnsmasq being enabled by NM), I'm closing this a Fix Released.

Title:
When eth0 is unmanaged, system connections for other NICs aren't
displayed nor used
Status in “network-manager” package in Ubuntu:
Fix Released
Bug description:
Binary package hint: network-manager
If eth0 is assigned a static IP in /etc/network/interfaces,
then NM doesn't display nor use any system-connections defined for *other*
NICs.
I include the output from trying to add a new connection:
1. I run nm-connection-editor.
2. I press the Add button, fill some static IP info, ***check the [v]
Available to all users*** checkbox, and click Apply.
(the "Invalid setting IPv4 Settings" message is displayed while filling the
dns server)
3. The result is that without getting any error message on the GUI,
the connection is not displayed at all. So one would think that it was
discarded; however, if I look at the file system, it's there, but it's
like NM doesn't read it at all. See the output of "sudo ls -lha
/etc/NetworkManager/system-connections/" below:
Follows the terminal output of the above steps:
