AsyncEventFilterBuilder.deploy raises "Invalid web3 argument" when provided with AsyncWeb3 instance

Providing an instance of AsyncWeb3 to async event builder

AsyncEventFilterBuilder.deploy(AsyncWeb3)

raises ValueError: Invalid web3 argument: got: <web3.main.AsyncWeb3 object at ... It comes from _utils.events:L450, where there is a check if not isinstance(async_w3, web3.Web3):. Shouldn't it check for web3.AsyncWeb3 instead?

Providing non-async instance of Web3 leads to other coroutine related issues. Changing the check to its negation if isinstance(async_w3, web3.Web3): delivers expected behaviour.
