[MC-6341] Pistons stay extended when using with redstone torches or daylight detectors.

I was creating a redstone firework shooter in creative mode. I had to invert the signal into a deactivator (meaning I used a redstone torch to make the signal turn off the piston,) but I noticed when a sent the signal, the piston did not retract. It only turned off when I removed the redstone torch. It had the same reaction with a daylight detector.

Please attach some screenshots.

As you can see in my attachment, the piston has not retracted, though the redstone torch is in off-state.

But the piston should be on. Quasi-connectivity means that the lever is still sending power to the piston.

Are you sure? Look, the lever is powering the wood plank, the wood plank can only send it's power to something touching it. It can not send power diagonally.

From the wiki:
"In addition to the methods above, a piston can also be turned ON if one of the methods above would activate a powered mechanism in the block above the piston, even if there is no powered mechanism there (even if the block above the piston is air or a transparent block), but only when the piston receives a block update. This is known as piston connectivity (the piston is "connected" to the block above for the purposes of activation)."
(This is the essential ingredient in many block update detectors and Mojang has basically said they won't fix it.)
