Duplicate array objects for cyclic many to many relations

I have a many to many relations between two models. When I create 2 level cycle then duplicate objects are added to array. For example suppose I have two models User and Intersts and many to many relation between then like this:

User.schema = {
  name: 'User',
  primaryKey: 'id',
  properties: {
    id: { type: 'string', default: '' },
    name: { type: 'string', default: '' },
    interests: { type: 'list', objectType: 'Interest', default: [] },
  }
}

Interest.schema = {
  name: 'Interest',
  primaryKey: 'id',
  properties: {
    id: { type: 'string', default: '' },
    name: { type: 'string', default: '' },
    interestedUsers: { type: 'list', objectType: 'User', default: [] },
  }
}

When I try to insert following data with realm.create(<modelName>, <object>, true) it does that correctly: http://pastebin.com/pE1FFd5x

But on adding following data multiple entries for same interest is created for user: http://pastebin.com/FFLbR5CR

A demo project showing the issue is here: https://github.com/shahankit/realm-duplicate

Will hopefully be able to start working on adding virtual properties/backlinks/#343 in the next two weeks.

We now have underlying core and object store support for computed properties and I hope this will make it into one of the next few releases, assuming we don’t run into technical issues in how we expose this functionality in the js layer.
