Doctrine with two Entitymanagers looks at wrong database - doctrine

Question

I did follow these rules of setting up a second connection and a second entity manager in doctrine. The "default" database is called revee and the "source" database reveesrc.
What works
When I dry-run a migration with this code in the postUp() method:
/** #var EntityManager $em */
$em = $this->container->get('doctrine.orm.entity_manager');
/** #var EntityManager $emSrc */
$emSrc = $this->container->get('doctrine.orm.source_entity_manager');
var_dump($emSrc->getConnection()->getDatabase());
$dates = $emSrc->getRepository('App:Dates')->findAll();
Weirdly, I get the database reveesrc written our correctly! Meaning that the mapping from the connection to the entity manager works just fine.
What doesn't work
However, the next line produces the error.
Base table or view not found: 1146 Table 'revee.dates' doesn't exist"
As dates was defined in the Entity folder attached to the second source entity manager I thought doctrine would know where to look for the table. What do I have to do to map the Entity to the other source database?
doctrine.yaml
parameters:
# Adds a fallback DATABASE_URL if the env var is not set.
# This allows you to run cache:warmup even if your
# environment variables are not available yet.
# You should not need to change this value.

If anybody experiences the same problem, I fixed it by specifying the table explicetly in the entity, prefixing it with the database. If anyone knows if that is not the correct way of solving it I would be interested.
<?php
namespace App\Entity\Src;
use Doctrine\ORM\Mapping as ORM;
/**
* #ORM\Entity(repositoryClass="App\Repository\DateSrcRepository")
* #ORM\Table(name="reveesrc.dates")
*/
class Dates
{
