Adding cmp-path breaks completion

[nimeco]

Greetings, I noticed that pressing <Tab> on the Cmdline mode stopped working, even though wildmenu was set to on. I thought the mappings were the culprit and using :verbose map <Tab> only showed:

s  <Tab>       * <Cmd>call v:lua.cmp.utils.keymap.set_map(11)<CR>
        Last set from Lua

Tried locating where v:lua.cmp.utils.keymap.set_map was being set and it turns out to be in nvim-cmp\lua\cmp\utils\keymap.lua, line 228 here. Added a print to see what was being set (is there a better way to debug those?) and the outcome was:

mode:i lhs:<Up> rhs:<Cmd>call v:lua.cmp.utils.keymap.set_map(1)<CR>
mode:c lhs:<Up> rhs:<Cmd>call v:lua.cmp.utils.keymap.set_map(2)<CR>
mode:i lhs:<C-E> rhs:<Cmd>call v:lua.cmp.utils.keymap.set_map(3)<CR>
mode:c lhs:<C-E> rhs:<Cmd>call v:lua.cmp.utils.keymap.set_map(4)<CR>
mode:c lhs:<S-Tab> rhs:<Cmd>call v:lua.cmp.utils.keymap.set_map(5)<CR>
mode:i lhs:<C-P> rhs:<Cmd>call v:lua.cmp.utils.keymap.set_map(6)<CR>
mode:c lhs:<C-P> rhs:<Cmd>call v:lua.cmp.utils.keymap.set_map(7)<CR>
mode:i lhs:<C-N> rhs:<Cmd>call v:lua.cmp.utils.keymap.set_map(8)<CR>
mode:c lhs:<C-N> rhs:<Cmd>call v:lua.cmp.utils.keymap.set_map(9)<CR>
mode:i lhs:<CR> rhs:<Cmd>call v:lua.cmp.utils.keymap.set_map(10)<CR>
mode:s lhs:<Tab> rhs:<Cmd>call v:lua.cmp.utils.keymap.set_map(11)<CR>
mode:i lhs:<Tab> rhs:<Cmd>call v:lua.cmp.utils.keymap.set_map(12)<CR>
mode:c lhs:<Tab> rhs:<Cmd>call v:lua.cmp.utils.keymap.set_map(13)<CR>
mode:i lhs:<C-Space> rhs:<Cmd>call v:lua.cmp.utils.keymap.set_map(14)<CR>
mode:c lhs:<C-Space> rhs:<Cmd>call v:lua.cmp.utils.keymap.set_map(15)<CR>
mode:i lhs:<C-F> rhs:<Cmd>call v:lua.cmp.utils.keymap.set_map(16)<CR>
mode:c lhs:<C-F> rhs:<Cmd>call v:lua.cmp.utils.keymap.set_map(17)<CR>
mode:i lhs:<Down> rhs:<Cmd>call v:lua.cmp.utils.keymap.set_map(18)<CR>
mode:c lhs:<Down> rhs:<Cmd>call v:lua.cmp.utils.keymap.set_map(19)<CR>
mode:i lhs:<C-D> rhs:<Cmd>call v:lua.cmp.utils.keymap.set_map(20)<CR>
mode:c lhs:<C-D> rhs:<Cmd>call v:lua.cmp.utils.keymap.set_map(21)<CR>

So, <Tab> is being set to something in Cmdline mode, even though :verbose map <Tab> didn't show it. (Why's that?) I don't really know if the above has any relation with the issue.

So I went for the minimum config and found out that, when adding nvim-cmp with cmp-path, the issue would happen. <Tab> is set in config-cmp.lua but it seems it's not respecting that config.

Also, opening Neovim without doing anything, since it lazy loads the plugin because of event being set(? I suppose, new at packer), if I enter the Cmdline mode, autocompletion works. After going into Insert mode and triggering it an event, autocomplete breaks. Disabling cmp-path makes Cmdline autocomplete work back again.

• Vim type (vim/gvim/neovim): Neovim
• Vim version: v0.7.0-dev+1201-g5760cf87b

Thanks a lot!
