Observers are missing their cooldown.
Observer can power directly after the tick it already power, sending a constant power if made to update every tick
This is a huge flaw and it breaks about 80% of doors
Example:
1.13pre-7: piston is powered for 2 ticks (4 gameticks)
1.12: piston is powered for 1 ticks (2 gameticks)
Example 2:
1.13pre-7 : right piston is extended same way as left piston
1.12: right piston pulses twice
Example 3:
part 1: Piston
1.13pre-7: Piston is constantly powered
1.12: Piston pulses
part 2: Dust behavior.
1.13pre-7: the redstone dust never unpowers
1.12: the redstone dust turns on and off
+ observers powers more times/minute in 1.13pre-7 compared to 1.12

This bug was introduced in 1.13-pre4, and affects all subsequent versions.
I'd like this fixed before the release.
The clock driving this circuit is common. The top observer that detects the output repeater outputs a constant signal. It would be the same if the lower repeaters were a continuation of the rails.

This mechanic breaks alot of redstone creations for no reason. It was a really useful and intuitive mechanic widely used by redstoners, and accidentally removing it will just pisses of people as their redstone breaks for no reason.
Confirmed in 1.13, turned a lot of redstone circuits into clocks and tanked my Patreon servers tick rate as a result.
Confirmed in 1.13-pre8: Observer does not work as it should.
