DISCLAIMER:
I am uncertain if this bug has already been reported, but couldn't find anything on the browse page.
How to replicate:
Place 2 observers (an observer clock) running into a redstone lamp, being observed by an observer. The final observer will pulse despite the redstone lamp never visually changing state (nor the blockstate changing in F3).
1.20.2:
Expected Behaviour:
Final observer has no output as the redstone lamp is not changing state.
Discovered Behaviour:
Final observer pulses in sync with an identical system with the lamp replaced by a noteblock.
Potential Cause:
The lamp is turning on and off in one tick, scheduling the observer to pulse but no visual change. This result cannot be replicated if the lamp is powered or a second (misaligned) clock is also powering the lamp.

This duplicates MC-200887. It's unclear if this is working as intended or not.
I will link a video of it here: https://youtu.be/qXYIodHPD7Y
Notes: The single observer is still going on and off, even though the lamp is always powered (you can see this with the f3 menu)
