Target blocks visually redirect Redstone dust, but don't actually

Target blocks visually redirect Redstone dust, but don't actually redirect it. It's not a huge issue, but could be a extreme source of confusion for people learning Redstone.

To reproduce build what's in the included screenshot. The contraption with the Redstone light off is the intended mechanic. The daylight sensor is redirecting the dust away from the iron block, keeping the light from getting powered.

In the other contraption the target block is appearing to redirect the dust like the daylight sensor does, but the light is still powered. This shows that the block doesn't actually redirect the dust. Other tests done by anyone with a basic understanding of Redstone will show the same affect.

Again, this is not a huge issue (especially with target blocks now conducting Redstone and therefore being placed in situations where this issue won't be as apparent), but it's still a source of confusion and frustration.
