Selector-based event loops returns `_SelectorDatagramTransport` which inherits `asyncio.Transport` instead of `asyncio.DatagramTransport`.

isinstance(transp, asyncio.DatagramTransport) fails.
It doesn't affect the actual execution since `transp.sendto()` and `transp.error_received()` are correctly implemented.

The bug doesn't affect Windows proactor-based implementation.

The fix is relatively easy, a champion is welcome!
