I'm not saying, the /etc/network/interfaces parser couldn't be improved
(it's actually pretty shitty). That said, I'm not sure if your problem
is really caused by that or if it's just a red herring.

Anyway, if want to mark a device as unmanaged by NM, you have more
explicit ways then relying on the eni parser.
E.g. you could create a conf file like this:

# cat /etc/NetworkManager/conf.d/unmanaged.conf
[keyfile]
unmanaged-devices=interface-name:bridge
