Hoppers always enabled with redstone deactivation.

Hi,
I wanted to remove items from the itemflow in a hopper pipe. I tried various redstone connected to hoppers around the pipe but could not stop the items from flowing away. Redstone activated block,, redstone into the hopper, redstone going past the hopper and repeater into the hopper with no effect at all.
It seems like old hoppers still work as intended.

Newly placed hoppers are always enabled.

I noticed this first now because of the above strange behavior.
Hope this was helpful.

Regards,

Marcus
