Incorrect union assembled from imported typedef

[alexandrmazur96]

Here I would expect array{id: int, something?: int} but array{id: int, something: int} is inferred:

However, when types are declared directly on the using class union type is inferred as expected:

I found these snippets:

<?php

namespace A\B;

/**
 * @psalm-type _A=array{
 *      id:int
 * }
 *
 * @psalm-type _B=array{
 *      id:int,
 *      something:int
 * }
 */
class Types
{
}

namespace A;

/**
 * @psalm-import-type _A from \A\B\Types
 * @psalm-import-type _B from \A\B\Types
 */
class Id
{
    /**
     * @psalm-param _A|_B $_item
     */
    public function ff(array $_item): void
    {
        /** @psalm-trace $_item */
    }
}

Psalm output (using commit 9dfdcbe):

INFO: Trace - 32:0 - $_item: array{id: int, something: int}
