When configuring a standard network as source or target the same
interface would be pre-selected as firewall interface when editing an
existing rule.

In case an existing input rule with an configured firewall interface
should be changed, the same network device has been pre-selected in the
standard networks dropdown box.

This easily confuses users and may lead to false configurations when
saving an edited rule.
