Not finding type specifications in make_dataclass

Given the following script:

from typing import NamedTuple
from dataclasses import make_dataclass, dataclass

Emp1 = NamedTuple('Emp1', [('name', str), ('id', int)])
r1 = Emp1('raymond', 'xyz')

Emp2 = make_dataclass('Emp2', [('name', str), ('id', int)])
r2 = Emp2('raymond', 'xyz')

class Emp3(NamedTuple):
    name: str
    id: int

r3 = Emp3('raymond', 'xyz')

@dataclass
class Emp4:
    name: str
    id: int

r4 = Emp4('raymond', 'xyz')

mypy only finds three of the four type errors:

$ mypy --version
mypy 0.650
$ mypy nt_example.py
nt_example.py:5: error: Argument 2 to "Emp1" has incompatible type "str"; expected "int"
nt_example.py:14: error: Argument 2 to "Emp3" has incompatible type "str"; expected "int"
nt_example.py:21: error: Argument 2 to "Emp4" has incompatible type "str"; expected "int"

Reproduce the example with mypy 0.650, focusing on the make_dataclass call and the constructor it generates. Trace how mypy handles dataclasses.make_dataclass, then add a regression test based on the script; done means the invalid string argument for Emp2 is reported along with the other three errors.
