Piston monostable circuits no longer work. I do not care if this is technically working as intended or not, it needs to be reverted back. There are so many redstone builds that no longer work because of this issue.

The piston timings seem to have changed. This seems to be happening because extension happens sooner (compared to the red stone update). Related issue: MCPE-27040 seems to be happening because retraction happens sooner (compared to red stone update).

This isn't a duplicate of MCPE-16641. The mechanism here does not try to power the piston from the front, instead what powers the piston is the block to the side (which is weakly powered by the redstone dust on top of it). This mechanism works correctly in build 1.2.2.3.
