Bug report

Accordint to PHPStan doc https://phpstan.org/writing-php-code/phpdocs-basics Using @return static along with the self native typehint means that the method returns a child class

As of 1.10.48 (not present on 1.10.47) return types at level 3 report an error like:
Method Foo::create() should return static(Foo) but returns Foo. using this example:

interface IFoo
{
	/** @return static */
	public static function create();
}

class Foo implements IFoo
{
	public static function create(): self
	{
		return new self();
	}
}

I don't think this is an error.
If it is an error in the code, how it could be solved?
If it is not an error, then it is a bug?

Thanks for PHPStan, it is geat!
