Just uploaded my log file. I had to zip it because otherwise it would exceed the 10MB limit
This bug still affects me on 1.21

Can confirm in 1.20.4, also applies to the `minecraft:generic.movement_speed` attribute in addition to potion effects
@syarumi Yes, pretty much, but it would be good to add to that issue that it is also an issue with attribute modifiers, not just potion effects.
This is a feature request, not a bug report.
Issue persists in latest pre-release. In fact, the issue is even worse now as the items refuse to manually stack.
