Is this an actual bug and is it actually going to be fixed? It looks like it's been reported a lot for well over 6 months so it'd be nice to know if there's plans to fix it or if we should just accept that cactus's won't do damage from the top anymore.
No. You can literally just put down a slime block and walk around the edges of it and then jump around on the edges, corner and center to see what I'm talking about.
I am pretty sure it affects more than just XB1 version. I run parkour maps on my realm and have players from several systems that play on my maps. This problem with the slimes seems pretty universal on Bedrock edition from what I've seen.
Three images added. Let me know if you need anything else

Kelp placed by a player gets a random age, as does bamboo. If weeping vines also gets a 0 age when placed by a player it should also be fixed.
