Symfony version(s) affected: 3.4.12

Description

I'm not sure if this is intentional or a new issue that has just come up, but it seems like any service that is declared as lazy is not shared anymore.

How to reproduce
Declare any service as lazy and then call it more than once any where, you will see that it is initialized more than once (__construct is called many times)

This issue happens today after I updated my code.

Edit: I tested on a very class with nothing but the __construct and another simple method, I can confirm that this happens on my current installation. If further checking is needed I can try with a barebone installation of Symfony.
