Package fixture doesn't respect dependency

[voronind]

1. Package fixture doesn't tear down after dir "exiting".
2. Package fixture doesn't use another package fixture depends on it. See comment in pytest output.

Ubuntu 20.04, pytest==5.4.3, python 3.6

from pytest import fixture

@fixture('package')
def company():
    print('\ncompany == 1')
    yield 1
    print('\ncompany == 1 tear down')

expr/test1/test_1.py

def test_1(company2):
    assert company2 == 1

expr/test2 is same but 2 instead of 1

expr/conftest.py

from pytest import fixture

@fixture('package')
def company2(company):
    print('\ncompany2 == ', company)
    yield company
    print('\ncompany2 == ', company, ' tear down')

I believe this should be fixed with #11646. Please test pip install pytest==8.0.0rc1 and let us know if not!
