Limit Water/Lava Range

Right now it's possible to have an infinite long line of lava or water if either placed really high or making a staircase for the water/lava to run down and just break the 8th block so it can repeat itself.

Water/lava should never be able to pass that 8th block, regardless of if it's running down a staircase or falling from the sky.

If you went to the top of the minecraft world, place water/lave, that source block would generate liquid all the way to the bottom.

Instead of this behavior, the liquid should just evaporate when it has reached it's max range of 8 blocks away from its source.

This makes much more sense intuitively and wouldn't hinder players in any of their water contraptions.

It would also mean that griefing with these two cobblestone-generating liquids would be much less viable.
