Read projection will never fire allowRead('projection')

Read projection will never fire allowRead('projection')

// posts - is real collection
backend.addProjection('posts_projection', 'posts', {id: true, title: true});

backend.allowRead('posts', async (docId, doc, session) => {
  // Read posts_projection will fire this callback
  return true;
});

backend.allowRead('posts_projection', async (docId, doc, session) => {
  // We will never reach here and is still possible to read posts_projection
  return false;
});

In derbyjs-app:

 model.query('posts_users', {}); // Will fire allowRead('posts') instead of allowRead('posts_projection'), but this is wrong

Is this a bug?

But this will work as expected:

backend.allowUpdate('posts_projection', async (docId, oldDoc, newDoc, ops, session) => {
  return true;
});
