plugin only works on the first file opened

just installed this and was testing it, i noticed that the plugin only works on the first opened file with git merge conflicts. runing `:GitConflictListQf` then moving to next qf item if its in a different file the plugin doesnt register keymaps or highlights. i dont know if this is just me, if anyone knows a fix please let me know.

the minimal config is:

```lua
return {
"akinsho/git-conflict.nvim",
lazy = false,
version = "*",
config = true,
}
```
