Shouldn't be, actually, if it has an IOR. This has been discussed in the
past. The reason that it shouldn't be transparent is that what you see
through it isn't what's directly behind it. Same idea as when a reflected
object reflects the sky - just because you see the sky through it doesn't
mean it should be transparent. Making those areas transparent would make it
unrealistic when layered in a 2D editor on top of a background image.

In any case, it's intended to be that way. (Though I don't know why it's
non-transparent during the first few steps.)
