MC-9186Water does not leak through leaves and regular stairs but upside down stairs
Water (still or flowing) does not drip through leaf blocks, even though rain does.
Water also seems not to penetrate certain other blocks that it should. These are all transparent variants as far as I can tell. Stairs - stop leaks, upside down stairs - leak; upper slabs - leak, lower slabs - don't leak; ice - doesn't leak; and even water itself, if you have a free-floating water block, it doesn't so much as dribble.

The animation for rain leaking through upside-down stairs and rain dripping through leaves is different. The stairs actually look leakier IMO. Something is wrong. Please reopen.
In addition, water (still or running) does NOT drip through anything other than upside-down stairs. I have a test building with normal stairs, upside down stairs, glass blocks, and leaves, and with spring blocks above each. Only the upside-down stairs leak at all! Mac Os 10.5.8. I've reported that separately as MC-9186

Not tested on everything, but if something does not work right, that just means a bit more logic into that if.
I have a leaky roof of brick stairs, rightside-up, dripping from the upper seam (not the lower, apparently). FWIW, it seems similar to the way light "leaks" through the seams on stairs as well. v1.5
Edit: Actually, it might be more accurate to say that it drips from the joins where there is an air-block to either side of it
Further Edit: It occurs to me now that I did NOT see this when the roof was wood, only after I switched to brick
That description is a bit difficult to understand, could you attach a screenshot which shows the setup?

Can't really show the "drip" without video

For me, on 1.5, both wood and brick stairs produce similar effect. And while the effects is a little bit like "why do they leak?", it is actually a different issue, and probably will be considered a feature.
At least I could not see any water effects (well) below the stair blocks (unless they were also horizontally right next to a stairs block). Such drops would have indicated "leaking", which this particular JIRA issue is about.
Technically, at least what I saw, was not the dripping (droplets drop down from block's bottom side), but "splashes" (splash up and back down on block's top surface). However, the splashing (and dripping) only consider a single level for the whole block to start from, and since stairs have two levels on the "up" side, it works a little bit better when the effect starts at the half-block level. For the other taller side of stairs, this means the splashes will be inside the block. And that is what at least I could see, the rare splashes that started near the inner surface.
It is possible to "fix" that (as the necessary methods to get the proper surface do exist), but it might be a bit inefficient, and it would certainly be worthy of another issue, for Mojang to decide.
This issue still in 1.5.
