I was using /fill to place repeaters with a 4-tick delay, but when I placed a redstone block in front of the repeaters the delay seemed like it was only 1-tick. When I tapped on the repeater to change the tick delay it worked properly again.

Steps to Reproduce:

1. In the chat type "/fill ~ ~ ~ ~4 ~ ~ unpowered_repeater 15" (without quotes)
2. Place a redstone block in front of the line of repeaters to power them all.

What I expected to happen:
The repeaters would power each with a 4-tick delay.

What actually happened:
The repeaters powered up faster than they were supposed to. It seemed like 1-tick for each repeater.

This happened with command blocks executing the command as well, and using /setblock or /clone doesn't help. The delay is still inconsistent.
