Droppers and Dispensers aren't triggered by 1 or 2 tick pulses

Pulses of 2 or less ticks have no effect on dispensers

Repro Steps:
1. Create a 1 or 2 tick clock or pulse limiter, such as a loop of 2 Repeaters each on 2 tick setting. (see attached image)
2. Connect it to a dispenser and place some items in it.
3. Activate the clock/pulse limiter.

Result: No item is dispensed.

Expected Result: Any length pulse will activate the dispenser (which was the behavior prior to Snapshot 13w01a)

Power the dispenser and it will trigger with the pulse. it was that way before the snapshot in 1.4.6 so i don't know if its a bug or not

I also found this. I even tried activating the dispenser with a button and had no luck. I am using 13w01b.

The dispenser WILL activate with the first pulse, but it does not deactivate fast enough to be triggered by the second pulse.

I'm attaching a screenshot of a configuration that works just fine without any sacrifice in speed.

Works as if it were only hooked up to the pulsing repeaters.

MAY TAKE A FEW TRIES AT FIRST! Just keep switching the delay on the repeater behind the dispenser.

In the last snapshot, you can use the comparator instead of a clock to activate the dispenser.

Also happens with Lamps.

The lamp is on for slightly longer than the pulse, so it always stays on.

Using a clock that uses a 1 tick pulser from torches will cause a dispenser not to fire. When using a traditional 2 repeater method does work for me.

This seems to be fixed in 13w10b. So dispensers and droppers both get triggered by 1 tick pulses and 1 tick clocks (2 ticks cycle), however a comparator clock only triggers them once if they are placed to close to the output of the comparator. I haven't tested good enough, but it seems that the dropper or dispenser has to be more than 2 blocks away from the block in front of comparator to get triggered multiple times.

Resolving as fixed, with MC-11189 detailing the new problem.
