Fortune does work on leaves, it just has a small effect which should probably be increased. According to the wiki https://minecraft.fandom.com/wiki/Fortune fortune has a smaller effect on jungle saplings than it does on other saplings, which seems to be what I've seen from my own experience.

I ran a test in which I cut down 16 dark oak trees and used a netherite hoe to break all of their leaves, twice. The first hoe had fortune III, and the second hoe was unenchanted. Since neither hoe had unbreaking, I could tell how many leaf blocks were broken by each hoe. I don't know how many despawned naturally, but it is likely in the ball park of 1-2% and therefore not significant.

First test (fortune III, 1717 leaf blocks broken) results:
Apples: 14 or 1/123
Saplings: 168 or 1/10.2
Sticks: 76 or 1/22.6

This was similar to the values listed in the wiki:
Apples: 1/120
Saplings: 1/10
Sticks: 1-2 1/30 or 1/20

= = = = =

Second test (no fortune, 1711 leaf blocks broken) results:
Apples: 9 or 1/190
Saplings: 97 or 1/17.6
Sticks: 57 or 1/30

This was similar to the values listed in the wiki:
Apples: 1/200
Saplings: 1/20
Sticks: 1-2 1/50 or 1/33.3

My results appear to suggest that the fortune enchantment works as described for dark oak leaves spawned on a tree grown from saplings and broken with a hoe, with an error probability lower than 2σ.

I wonder if this is caused by MC-136435?

I have found more examples of this bug occurring, different versions of the game but always with a server hosted by their computer.

I'm not sure. I used the file server.jar to run Minecraft as a server, and connected to it via the multiplayer interface. The world was played in singleplayer in 1.13 versions and later migrated to the server.

I have re-created the issue. Also I realize I made a mistake. The issue happens in 1.13, not 1.13.1. I tested it in 1.13.1 and it did not occur.

I have discovered that my world's seed has been changed from -8264751760597529176 to -7963587952799384041. That would explain the issues, but I can't find any reason the seed would have changed. I have done nothing to provoke it. I have never attempted to change my seed. All I have done is change versions several times and migrate my game to a server. And the seed changed at some point when I hadn't changed the version.

No, I have not touched it.

The game saves automatically ever few seconds or so.

Can you provide a screenshot? You can view abandoned mineshafts easily in spectator mode. Try to show a point where multiple different structures meet up at once.

It looks pretty normal to me. Abandoned mineshafts are very common.

It makes perfect sense. If it gave you the effect underwater, it would last forever. It is supposed to only give you an extra ten seconds of breath.

My turtles wouldn't hatch for over 6 hours. I finally discovered that they only progress near the end of night, so you can't sleep or they won't ever hatch. The wiki says nothing of this and I haven't heard it from anyone else, so it's only my own experience that I am basing this on.

This isn't a duplicate and it isn't resolved. The issue it is linked to as a duplicate has a resolution that does not apply to this report. The solution indicated for the other report is that it is an invalid report because downgrading your game version is not supported. This, however, is a report that a bug happened when upgrading the game version. Unless upgrading is also not supported, the bug is valid. Furthermore, it applies not just to a narrow range of snapshots, but rather to all versions up through 1.7.10 when upgraded to any 1.8+ version. It is still unresolved because no version has yet been released that allows a safe version upgrade for old saves.

Possibly what is causing issue: '0' position is not being used. If the container has 32,768 positions going from 0 through 32,767 and you skip the 0 position, you have only 32,767 usable positions.

I would test by attempting to fill a 33x31x32 area (32,736 blocks) and also a 151x31x7 area (32,767 blocks). Just trying different areas and seeing exactly how close you can get will help reveal how large the container really is.

90x28x13=32,760
32x32x31=31,744
32x32x16=16,384
31x33x16=16,368

Resolved in snapshots. Clever resolution: you can no longer place a block inside the double plant.

I tried extensively to replicate this bug in 1.11 and failed. Many times I saw zombie pigmen attacked by other mobs but not once did they ever aggro to the player. I haven't seen this bug since 1.8.

I see an easy fix for this. Have the client ping the server each time it breaks a block, and make the server agree or disagree. If the server disagrees, the client puts the block back. You don't have to ping every client, only one client has to ping the server.

For clarity, I will write this post using the following terms:
End Gateway: the portal that spawns on the main island near the obsidian pillars after you kill the dragon
End Return: one of the twenty portals strewn about the outer end islands which links to an End Gateway once the gateway is activated

If you go through an End Return before its End Gateway has been activated, it will send you to the End spawn point, the place where you come in initially on the End Mainland, on the small square obsidian platform.

I have on multiple occasions had an ender pearl go into the portal without taking me with it. When I finally get through the portal, I would invariably take a single hit of ender pearl damage as though I had thrown it onto the ground. Once I went through the End Gateway after the first ender pearl had failed, and I was teleported quite a ways away from the End Return on the other side. I suspect that the ender pearl was teleported through as a moving projectile and when I materialized on the other side, the ender pearl continued on its trajectory until it hit the ground a ways away.

This could explain what happened to you if you spawned on the obsidian platform and were immediately teleported to the side of the End Mainland where the ender pearl hit. What happened to you probably isn't very common, but the Ender Pearl bug is common enough that it worries me.

The new one spawns but the old one does not despawn. I discovered this in single player.

It works the same in an unmodified client. Proof in the second image.

I got the second image by summoning the dragon fresh after going to vanilla client, and performing the same steps as detailed in the OP. It works every time I try it.

I've been having this issue for as long as I can remember. I've never hit myself with an arrow, but thrown "arcing" objects consistently hit the player's head, especially eggs. I've also found that when shooting a bow from inside a minecart, the arrow easily hits the minecart, whereas a sword always ignores the minecart as it should.
