Unclear how to add a type to arguments taken by a short closure

[psalm-github-bot]

I found these snippets:

https://psalm.dev/r/2a616dac12

<?php

/**
@psalm-type ArrayType array{code: int, ...}
*/
class Test {
    /**
    * @var Closure(ArrayType): void|null
    */
    private ?Closure $test = null;
    
    public function setDefaultClosure() : void {
        $this->test = fn(array $arrayType) : null => $this->takeArrayType($arrayType);
    }
    
    /**
    @param ArrayType $arrayType
    */
    public function takeArrayType(array $arrayType): void {
    }
}

Psalm output (using commit 16b24bd):

ERROR: ArgumentTypeCoercion - 13:75 - Argument 1 of Test::takeArrayType expects array{code: int, ...<array-key, mixed>}, but parent type array<array-key, mixed> provided
