Weird water bug

bug for 1.17.0:so this is an small but annoying bug that stops some automated farms that use water from working. So the water doesnt flow down for some reason it goes down and takes a random turn to the left or right even if there is a block there to stop it from going to the wrong direction and it will Stay like frozen trying to turn right or left so that means that the automated  farm cant be automated because the water is not going in the right way and thats anoying .BTW sorry for my bad english
