Passive mobs don't spawn if you're riding a horse

Passive animals should spawn in some newly generated chunks if the biome supports it, but I have found that if you're riding a horse then no passive mobs will spawn in newly generated chunks. This was tested (and very apparent) in a superflat world, where I explored a lot on horses.

Once I figured out the cause I started running on foot and sure enough, passive mobs began popping up on the newly generated chunks. This may occur whilst riding pigs or boats - might want to check the code for those. The logic might apply to minecarts, but obviously if there's rail there it's not newly generated chunks.

Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

Is this still a concern in the current Minecraft version 1.7.2 / Launcher version 1.3.4 or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

This no longer happens - it has been fixed or was never an issue. I was expecting passive mobs to spawn immediately on some newly generated chunks, but there can be quite a long delay. The short rendering distance for mobs didn't help either.
