incorrect contact assigment to services with passive checks

[yoshi314]

Describe the bug

I have a rather fancy logic of applying contacts or contact groups. The gist of it is as follows:

// service definitions
apply Service "whatever" { 
  (...)
  vars.notification.sms.extra_groups = [ "itdcr" ]
  (...)

  assign where host.address == "172.17.2.59"

}

and the notification code has something like this :

  if (service.vars.notification.sms.extra_groups) {
    user_groups += service.vars.notification.sms.extra_groups
}

Expected behavior

A passive check gets assigned the 'itdcr' contact group.

Actual behaviour

ALL services on host with that service get assigned the 'itdcr' contact group. I have no clue why this happens, i have observed the exact same behaviour with passive checks two years ago as well.

The passive check is the only that mentions the 'itdcr' user group in the entire icinga2 configuration.

I can provide trimmed down config if necessary, that just might take some time to cut it down to minimal working example.

cut it down to minimal working example

Yes, please!
