When you look at an enderman that is a holding stained glass block, the glass is opaque from nearly every angle.
From the remaining angles the block is not semi-transparent but fully transparent like normal glass blocks.

Is this still a concern in the current Minecraft version 14w07a / Launcher version 1.3.9 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 bug is still a concern in the latest SNAPSHOT (14w07a).

Faulty logic is being used to justify this being a bug. Regular glass works fine because it is alpha tested, not alpha blended. These are two different things. Alpha testing is supported on entities, alpha blending is not.

Per MC-34696, stained glass held by an enderman being opaque probably isn't a bug. However, the faces turning completely transparent from some angles may be a bug. Mojang will have to weigh in on that.
