Pistons powered by redstone on slabs is incorrect
When powering a piston with redstone, the piston the redstone is pointing into should be powered, not the one below it. See attached gif.
The bug doesn't happen for pistons south of the redstone.
Edit:
I have discovered that this bug happens differently depending on the axis, and which side of 0,0 the pistons are on. I have made a video showcasing this: https://youtu.be/TE1hoDIewVo
I also want to make it clear that I believe the top piston should fire, not the piston below, lifting the top one up.
This was performed in a redstone superflat world, originally created in 20w15a, and moved over directly to 20w18a, however, none of this redstone was created before 20w18a.

I was testing to see if a bug someone mentioned could be replicated (MC-182452). I sadly couldn't replicate their bug but whilst testing, I found another. The pistons on the bottom activate when they're not supposed to if placed in the way the second (now last) screenshot shows, but then work as intended with the first (now second til last) screenshot.
UPDATE: Added two screenshots. Seems to be random..? (or dependent on the coords of the block)
I've investigated more into my report in MC-182452 and it turns out it depends on which side of 0,0 the pistons are on. I've made a little video showcasing this on the 4 different corners from 0,0: https://youtu.be/TE1hoDIewVo
Might also be MC-182452.
Interesting. Could not reproduce your version but I found another bug when testing it. Might add.
I was unable to recreate the bug. You might want to include additional information such as operating system and Java version. You can also try describing the circumstances under which you found this bug, e.g. gamemode, single- or multiplayer.
I have edited to add a video showcasing the bug. This video shows the piston behaviour on each side of 0,0, in all 4 quarters of the world. Here: https://youtu.be/TE1hoDIewVo
