Surface GUI Transparency Glitch

I was playing Stickmasterluke’s Natural Disaster Survival, and I found a weird bug.

When you zoom in and your character has even a little bit of transparency, surface GUIs draw with full opacity.

Here’s it in action:

I doubt this is intended, so I though I would just report it.

It more than likely is intended, as SurfaceGUIs are rendered above other objects. I don’t know how they’re doing part-based occluding though. Probably a similar way to Decals, which I believe exhibit a similar problem.
