When putting a redstone repeater or comparator on top of a redstone block. they do not get powered. Vs when put a redstone torch or dust is activated.

I thought they would have been powered and I think they should be.

What happened, was they didn't get powered at all.

I dont know if its a bug or you want it. But if the redstone torch, redstone dust and powered rail are powered by sitting on top of a redstone block. I think the repeater and ccomparator should be powered also.

Thanks!
