I'm developing a mod that includes a type of translucent stair block.  Specifically, the block class derives from StairsBlock and returns BlockRenderLayer.TRANSLUCENT from the getRenderLayer method.  When viewed in the world, the bottom half of the stairs will, from some angles, render over the top half of the stairs.  I've attached a screenshot to demonstrate the issue.  This bug does not occur when getRenderLayer returns BlockRenderLayer.SOLID.
