Bug metal grill not visible through glass

[apollyon]

when you look through glass or glass doors at a metal grill block it looks like the block isn't there, this is a pure visual bug because when i open the glass door or fly through the glass blocks in buildmode i can see it again
just tested it with some other see through blocks and the same thing happens

This is a problem many openGL games have if they contain transparent textures.
A vertex behind an already drawn vertex isn't rendered at all, regardless if the drawn vertex is transparent or not.

Exactly this.

This is a pretty simple read if you are curious as to why.
