Rails powered by an unpowered source

Steps to Reproduce:

 1.Put a redstone block or lever(active state)

 2.Place a line of powered rails.(stop when the redstone signal doesn't reach the rail)

 3.Add 2 extra powered rails(which are off).

4.Put a repeater next to last "off" rail facing the rail.

schematic

{

[REDSTONE][ON][ON].......[ON][OFF][OFF][<REPEATER]

}

Observed Result:

Updating the area by PUT/DESTROY block near to the ON-rails will activate the 2 extra rails.

Or leave and enter the world,you'll find the 2 rails powered.

Breaking one of the ON-rails while 2 rails are ON, will toggle 2 ON-rails to OFF.

Expected Results: This shouldn't happen.
