Class level fixtures are not exeucting when using pytest-rerunfailure

[GangadharUppin]

Hi,
Could you pls help me to resolve some issue i m facing.
import pytest

@pytest.mark.usefixtures("setup_class")
class TestClassOne:

def test_one(self):
    # This test will PASS
    print("\n[TestClassOne.test_one] var =", self.var)
    assert self.var == "VALUE_FROM_FIXTURE"

def test_two_fail(self):
    # INTENTIONAL FAILURE
    print("\n[TestClassOne.test_two_fail] var =", self.var)
    assert False, "Intentional test failure"

@pytest.mark.usefixtures("setup_class")
class TestClassTwo:

def test_three(self):
    print("\n[TestClassTwo.test_three] var =", self.var)
    assert self.var == "VALUE_FROM_FIXTURE"

def test_four(self):
    print("\n[TestClassTwo.test_four] var =", self.var)
    assert isinstance(self.var, str)

This is my code
when i run test case using pytest -vs --reruns 1 --reruns-delay 2
test_two_fail will fail even in the rerun as expected.
Once this test is failed and exeucting TestClassTwo
i m getting error like "AttributeError: 'TestClassTwo' object has no attribute 'var'"

wht i m getting this issue ?
if i run pytest -vs it perfectly works fine.
