This happens a lot of the time with custom resources and I cannot figure out why. Custom permissions return wrong value with currentUser but returns correct value when loading user by uid. $this->currentUser is valid and the correct account. What's the issue/cause and resolution?

Example:

Wrong value:

$hasViewPermission = $this->currentUser->hasPermission(
    sprintf('view %s categories', $termGroup)
);
/// = false

Correct value

$user = User::load(\Drupal::currentUser()->id());
$hasViewPermission = $user->hasPermission(
    sprintf('view %s categories', $termGroup)
);
/// true

Role config

permissions:
  ...
  - 'view EDITORIAL categories'
