ConfigDicts aren't converted to dataclasses when specified in a list #441

The conversion back to dataclasses doesn't seem to work, when they are specified in a list.
Here is a minimal example.

from collections.abc import Sequence
from dataclasses import dataclass
from hydra_zen import store, zen, builds
from hydra_zen.typing import ZenConvert

@dataclass
class B:
    x: int

def app(dc: Sequence[B]) -> None:
    assert all(isinstance(b, B) for b in dc)

Config = builds(
    app,
    populate_full_signature=True,
    dc=[B(x=0)],
    zen_convert=ZenConvert(dataclass=True),
    hydra_convert='all'
)
store(Config, name="config")

if __name__ == "__main__":
    store.add_to_hydra_store()
    zen(app).hydra_main(config_path=None, config_name="config", version_base="1.3")

It fails with an assertion error. The entry in dc is a DictConfig.
Do I use zen_convert and hydra_convert the right way?
So far I reverted back to normal classes from dataclasses to solve this issue.

Thanks!
