Tilled dirt cannot be charged with redstone, power cannot be pulled through it with repeater

If you charge tilled dirt with redstone you cannot get a signal from the other side

What I expected to happen was that if I charged the block I could get a signal from the block

Steps to Reproduce:
1. Place a redstone power source (lever, redstone torch, etc.) next to a repeater
2. Face the repeater's input towards a tilled piece of dirt
3. Activate the power source and put a redstone piece on another side of that tilled block
4. Power is not given
