Multiple sub generics split up in wrong way

Bug report

• PHP version: 8.0
• PHP CS Fixer version: PHP CS Fixer 3.3.3-DEV
• the configuration used: return (new PhpCsFixer\Config())->setRules(['@Symfony' => true]);

Code snippet that reproduces the problem

/**
 * @return array<int, array<string, mixed>|Collection<string, mixed>>
 */
function example(): array
{
    // ...
}

I would expect PHP CS Fixer to do no changes.

Closing because I think this is a duplicate of #5921. If not, please let me know.
Also, can you please give #6063 a try and tell us whether it fixes the issue for you?

[gisostallenberg]

Yes #6063 fixes the issue. I fixed it in my code base for now by defining all parts separately, as in array<int, array<string, mixed>>|array<int, Collection<string, mixed>>.

Thanks for your response.
