Bug report
Using call_user_func([$class_name, 'myMethod']) where $class_name is of type class-string<Interface> reports error even if Interface declares myMethod.
Replacing $class_name with string containing name of class works.
Code snippet that reproduces the problem
Using variable as a $class_name fails https://phpstan.org/r/ec57ec5e-d5e3-47c2-8189-e2534bfee26f
Using class_name directly works https://phpstan.org/r/f63497b3-65c3-4e8a-9567-63556b63d8b7
Expected output
No error reported.
