[MC-23725] Given same redstone signal, dispenser which releases water does not retract.

Previous bug report was misunderstood to be a redstone bug report.
I am only reporting a bug which is a difference in dispenser behavior given a consistent redstone signal and location, only varying the dispenser state.

Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

Tested and updated. Same thing happens in 1.6.2

Only fails when redstone is on the block above the dispenser. Reliably collects water when powered from behind using repeaters, or the redstone is place directly on top of the dispensers. Seems like a quasiconnectivity issue. However, it is strange that the dispensers fire reliably when placing water, but not when collecting it.

Design E worked in some orientations or locations, but failed in others. Seems like a boundary or hashing problem.

Design F works, though as far as I know, the dispensers shouldn't fire at all, because the repeaters are just pointing at air. Quasiconnectivity again.

And Design G fails. So if the blocks above the dispensers are not powered, they should work properly, regardless of location or orientation. However, if the blocks above the dispensers are powered, then it may or may not work, depending on the size, location, or orientation.
