Dynamic call to BackedEnum::from() not recognized

[derrabus]

Bug report

When calling $someEnumClass::from($value), PHPStan does not recognize that the result is an instance of BackedEnum.

Code snippet that reproduces the problem

/**
 * @param class-string<BackedEnum> $enumClass
 */
function enumFromString(string $enumClass, string|int $value): BackedEnum
{
	return $enumClass::from($value);
}

https://phpstan.org/r/c2402ffb-9f95-4c22-b5f0-92316e622d1c

The error reported is:

Function enumFromString() should return BackedEnum but returns static.

Expected output

No errors.
