Multiple borders if "winborder" is enabled

[domma]

I set vim.opt.winborder = "single" to make pop-ups stand out more. After doing so all Telescope windows had doubled borders. I was able to solve that by passing

      defaults = {
        border = false
      },

to Telescopes setup function. This helps for the usual pickers, but not for the windows opened by this plugin. An example is executing LSP code actions. I have this in my config:

      extensions = {
        ["ui-select"] = {
          require("telescope.themes").get_dropdown {}
        }
      }
[...]
    require("telescope").load_extension("ui-select")

With that configuration code action choices are displayed in a pop-up windows, but it has doubled borders.

Is there a way to fix this?

[gavocanov]

require("telescope.themes").get_dropdown { border = false }

seems to fix the double border issue but when I use that it does not display the first item, every list starts with the second item.
