After some debugging this is my first attempt to fix this issue @nicolas-grekas 😊 Let's discuss it.
without the fix the test fails like this:
```
Testing Symfony\Component\Cache\Tests\Adapter\TagAwareAndProxyAdapterIntegrationTest
F 1 / 1 (100%)
Time: 28 ms, Memory: 4.00MB
There was 1 failure:
1) Symfony\Component\Cache\Tests\Adapter\TagAwareAndProxyAdapterIntegrationTest::testIntegration
Failed asserting that Array &0 (
'tag1' => 0
'tag2' => 0
) is identical to 'bar'.
