How to define FlagBag properties in api-platform?

[hafkenscheid]

With the introduction symfony/symfony#52699 in symfony/property-info v6.4.9, there is a break with this bundle.

Defining a flagbag property like so (source )

   /** @var FlagBag<Permissions>|null */
    #[ORM\Column(type: 'permissions_flagbag', nullable: true)]
    private ?FlagBag $permissions;

Results in errors like 'Class "Elao\\Enum\\T" does not exist' in combination with api-platform (3.*).

Maybe my definition (using @var) is wrong, or is this a bug and should we define a FlagBag as a Collection?

I don't have a solution yet, as I'm not sure why these extractor should always ignore non-collection types silently, which seems a BC break to me. But FlagBag isn't a collection for sure. Only a generic.
