see https://github.com/atk4/core/pull/318/files#diff-89ee4a0f4aa739755395c1d2786a6c142adb174f259e93bc3f964ee3870e983cR53

$surnameField variable is annotated by phpdoc with FieldMockCustom type which has getOwner method defined by TrackableTrait trait.

But phpstan reports:

Call to an undefined method Atk4\Core\Tests\FieldMock::getOwner().

It seems like the type phpstan uses is FieldMock instead of FieldMockCustom. Is it a bug?

I tried to reproduce https://phpstan.org/r/b5017736-958a-41bb-88b7-38208755e72b , but that try shows no errors...
