Internal mixin class incorrectly generating method.internalClass errors

[simon-tma]

Bug report

PestPHP uses functions from a mixin that is @internal. PHPStan is now flagging those method calls with method.internalClass errors despite the base class not being internal.

Example code:

        \expect($value)
            ->toBeArray()
            ->toHaveCount(3)
            ->toHaveKey('capacity')
            ->toHaveKey('space')
            ->toHaveKey('spaces');

Each method call here is now throwing:

Call to method toHaveKey() of internal class Pest\Mixins\Expectation from outside its root namespace Pest.

The playground link is a smaller version of this.

Expected output

No errors
