Incorrect NoSpaceBeforeNullabilitySymbol for typed properties preceded by static return type

[stefanfisk]

The following class generates SlevomatCodingStandard.Classes.PropertyDeclaration.NoSpaceBeforeNullabilitySymbol for array.

abstract class Test
{
    abstract public function begin(): static;

    protected array $field = [];
}

The issue does not appear when the return type is self.

I'm running v8.15.0.

Just found that this case also generates SlevomatCodingStandard.Classes.PropertyDeclaration.MultipleSpacesBeforeTypeHint for the static return type.

class Test
{
    public static function begin(): static
    {
        return new static();
    }

    /** @var array<string,mixed> */
    protected array $field = [];

    final private function __construct()
    {
    }
}
