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.

I also noticed this issue with a solid block with a button on top. 

I also got this to happen with observers facing away from the powered rail

This happens with any sort of redstone power. Including redstone dust, repeater, and comparator. It completely breaks all my complex designs that rely on this to work consistently. Please fix this.

It affects every version of Bedrock Edition

Seems as though the rails are not getting appropriate updates when powered/de powered (in this case powered rails (even in render distance)) Is this really 6 years old?? Can fixed I suppose with a forced block update but clearly unintended behavior.

I add the same problem but you need to have turned the power source on at least once before it happens, I think that's because the rail visually turns off but it “reminds” the powered state
