Permissions and forwarding not working with Fabric Mods

I have confirmed that ...

• all plugins and mods are up to date
• unable to reproduce in Spigot
• unable to reproduce in Forge

Plugins and Mods

Mods:
(alternatively to the Bukkit counterpart)LuckPerms-Fabric-5.4.140
Cobblemon-Fabric 1.6

Description

I am trying to restrict permissions for both Mods and Plugins, but even with the permission-forward setting I am unable to get both to work at the same time.

Using LuckPerms-Bukkit and forward-permission=true results in the Permissions for the cobblemon mod to not be working
Using LuckPerms-Fabric and forward-permission=reverse results in the permissions for EconomyShopGUI to not be working

Step to reproduce

Prerequisites:
Install EconomyShopGUI, LuckPerms-Bukkit and Cobblemon

Step 1) Assign the economyshopgui.eshop.* and cobblemon.* permissions to the default group
Step 2) Run the /editshop command, it should return a command usage information.
Step 3) Enter the /pokeheal command, it should fail due to missing permissions
Step 4) Set the permissions mentioned in Step 1 to false
Step 5) Run the /editshop command, it should not work due to the restricted permission
Step 6) Run the /pokeheal command, it should still fail due to missing permissions

Now uninstall LuckPerms-Bukkit and install LuckPerms-fabric
Also set the forward-permission setting in the arclight.yml to reverse

Step 1) Assign the economyshopgui.eshop.* and cobblemon.* permissions to the default group
Step 2) Run the /editshop command, it should not work due to missing permissions
Step 3) Enter the /pokeheal command, it should mention a fully healed party
Step 4) Set the permissions mentioned in Step 1 to false
Step 5) Run the /editshop command, it should not work due to the restricted permission
Step 6) Enter the /pokeheal command, it should fail due to missing permissions

I would expect that with the forward-permission feature I would be able to use one LuckPerms version for both, is that not the case or am I missing something?

Fabric has no Permission API built-in, so permission forwarding is unavailable for Fabric yet.
I am considering introducing the fabric-permission-api by lucko.

That definitely seems like something that should be included, since it kind of defeats the purpose of a hybrid server if users are unable to use both Spigot and Fabric plugins due to lack of permissions for one of them. At that point they might as well just run a pure Spigot or pure Fabric server.
