What happened?

Description

I ran across this when attaching a behavior to our entries.

Event::on(
    Entry::class,
    Entry::EVENT_DEFINE_BEHAVIORS,
    function(DefineBehaviorsEvent $e) {
        if ($e->sender->getType()->handle === 'questionType') {
            $e->behaviors['questionTypeStats'] = QuestionTypeBehavior::class;
        }
    }
);

For nested matrix entries this seems to throw the error

Invalid Configuration – yii\base\InvalidConfigException
Either sectionId or fieldId + ownerId must be set on the entry.

These entries have a fieldId + primaryOwnerId, but no ownerId.
