This issue is always reproducible with devstack.
I followed in bug description from 1 to 4 in the same order.
Issue ping to external network from vm first, ping will be sucess. Don't kill this ping and let it run continuously.
Then create a floating ip for this vm.
After this operation the previous ping will be in hung state.

So existing connection is lost.
