Water in stairs flows to the full side of the stair if there is a water source one block in front of and below it. The expected behavior is that the water from the ladder ignores the other water source (as it cannot reach it)

Steps to Reproduce:

• Place a stairs. 
• Put blocks on the not full sides of the stairs. 
• Put water on the stairs. 
• Place water just one block below and one block in front of the full face of the stairs. 

Observed Results:

The water plays the animation that it is flowing. 

Expected Results:

The water should not play the animation that it is flowing.
