Laravel Eloquent eager loading multiple relationships to same model generates multiple queries

I am currently working on a project where translations are a core feature. Implementing this with Eloquent has been a great experience so far, but the problem unfolds when a model has multiple relations to one model.

Say you have a model called Post:

<?php

namespace App;

// posts (
//    id
//    title
//    content
// )

class Post extends \Illuminate\Database\Eloquent\Model {
   public function title() {
      // posts.title -> translations.reference
      return $this->hasMany('App\Translation', 'reference', 'title');
   }

   public function content() {
      // posts.content -> translations.reference
      return $this->hasMany('App\Translation', 'reference', 'content');
   }
}

And a Translation model:

<?php

namespace App;

// translations (
//    id
//    reference
//    language
//    value
// )

class Translation extends \Illuminate\Database\Eloquent\Model {
   public function language() {
      return $this->hasOne('App\Language', 'id', 'language');
   }
}

And finally a Language model:

<?php

namespace App;

// languages (
//    id
//    code
//    name
// )

class Language extends \Illuminate\Database\Eloquent\Model { }

Then the following will successfully generate the expected output:

Post::with([
   'title.language',
   'content.language'
])->get();

[
   {
      "id":1,
      "title":[
         {
            "id":68,
            "reference":"5efd07083a002",
            "language":{
               "id":1,
               "code":"en",
               "name":"English"
            },
            "value":"Title in english"
         }
      ],
      "content":[
         {
            "id":70,
            "reference":"5efd0708f1c82",
            "language":{
               "id":1,
               "code":"en",
               "name":"English"
            },
            "value":"Lorem in English"
         }
      ]
   }
]

THE PROBLEM

Is that Eloquent sent duplicate (or very similar) queries to the database, making me wonder if there is a better solution:

[
   {
      "query":"select * from `translations` where `translations`.`reference` in (?)",
      "bindings":[
         "5efd07083a002"
      ],
      "time":186.14
   },
   {
      "query":"select * from `languages` where `languages`.`id` in (?, ?)",
      "bindings":[
         1,
         2
      ],
      "time":170.69
   },
   {
      "query":"select * from `translations` where `translations`.`reference` in (?)",
      "bindings":[
         "5efd0708f1c82"
      ],
      "time":171.93
   },
   {
      "query":"select * from `languages` where `languages`.`id` in (?, ?)",
      "bindings":[
         1,
         2
      ],
      "time":142.38
   }
]

After doing some research I could not find any answers to this problem except "it's not possible" with no explanation.

What is the best solution for this problem? Is there something that I am missing or is this really impossible?

Thankful for any answers!
