Description

#363 was closed, but when I try to set the window border to "rounded", no border is set:

I don't think this is a bug because the PR was clearly merged in, so I believe this must have something to do with my config, maybe with highlight groups or something. This affects both hover and action windows for me.

Example Code

vim.env.LAZY_STDPATH = '.repro'
load(vim.fn.system('curl -s https://raw.githubusercontent.com/folke/lazy.nvim/main/bootstrap.lua'))()

require('lazy.minit').repro {
  spec = {
    {
      'mrcjkb/rustaceanvim',
      version = '^5',
      init = function()
        -- Configure rustaceanvim here
        vim.g.rustaceanvim = {
            tools = {
                float_win_config = {
                    config = {
                        border = "rounded",
                    },
                },
            },
        }
      end,
      lazy = false,
    },
  },
}

I'm confused, did you close this discussion accidentally, or have you found a solution?
