When the method __post_init__ doesnt called?

[Maksim-Burtsev]

I found the issue where was conversation about an explict call of parent's __post_init__ method using super(), but if i try this:

from dataclasses import dataclass

@dataclass
class A:
    def __post_init__(self):
        print("A")

@dataclass
class B(A):
    pass

b = B()

it will output:

>> A

So, parents method works without explict call.

1. I don't understand what talk about was in this issue or problem with inheritence was solved?
2. In which case __post_init__ method of dataclass doesnt called?
