@realm/babel-plugin - new Realm.BSON.ObjectId() is invoked twice for property initialization

[takameyer]

How frequently does the bug occur?

All the time

Description

Give the following class:

export class Task extends Realm.Object<Task> {
  _id: Realm.BSON.ObjectId = new Realm.BSON.ObjectId();
  description!: string;
  isComplete: boolean = false;
  createdAt: Date = new Date();
  userId!: string;

  static primaryKey = '_id';
}

When two objects are created using:

realm.write(() => {
  return new Task(realm, description, userId);
});

The resulting _id is two increments higher between the first and the second item. Oddly enough, when using sync and Atlas, the _id is on increment smaller for the created items. This causes various issues when trying to make modifications when permissions are set.

Stacktrace & log output

No response

Can you reproduce the bug?

Yes, always

Reproduction Steps

This bug exists in the current example application in realm.

• Setup App Service and get the AppId
  • Enable username/password login
  • Enable Flexible Sync
    • Add userId to the queryable fields
    • Create a permissions object:

{
 "rules": {},
 "defaultRoles": [
   {
     "name": "owner-read-write",
     "applyWhen": {},
     "read": {
       "userId": "%%user.id"
     },
     "write": {
       "userId": "%%user.id"
     }
   }
 ]
}

• Configure the sync.config.js in the example app with the AppId
• Run the example application
  • Create a new user
  • Create a few items
  • Check the "done" checkbox

The Items will disappear
