Menu's scrollbar overlaping the documentation

[Sirikakire]

Make sure you have done the following

• I have updated to the latest version of blink.cmp
• I have read the README

Bug Description

In this picture, a part of the documentation has been hidden because of the scrollbar, I think it was because all of its border had gone because of my config

I frequently change my border style, but when changing to the last style in this picture, the scrollbar overlap the documentation (I also tested it with cmp and its never happend)

Honestly this is not big of a deal but if it would be great if the documentation can exclude to the side 1 more column to avoid the menu's scrollbar overlapping

Relevant configuration

menu = {
          scrollbar = true,
          scrolloff = 2,
          border = require("utils").border,
          winhighlight = "Normal:NormalFloat,FloatBorder:FloatBorder,CursorLine:PmenuSel,Search:None",
          draw = {
            padding = 1,
            gap = 2,
          }
        },

U.border = vim.b.doc_border_type == "single" and {
  { "╭", "FloatBorder" },
  { "─", "FloatBorder" },
  { "╮", "FloatBorder" },
  { "│", "FloatBorder" },
  { "╯", "FloatBorder" },
  { "─", "FloatBorder" },
  { "╰", "FloatBorder" },
  { "│", "FloatBorder" },
} or vim.b.doc_border_type == "double" and {
  { "╔", "FloatBorder" },
  { "═", "FloatBorder" },
  { "╗", "FloatBorder" },
  { "║", "FloatBorder" },
  { "╝", "FloatBorder" },
  { "═", "FloatBorder" },
  { "╚", "FloatBorder" },
  { "║", "FloatBorder" },
} or vim.b.doc_border_type == "padding" and {
  { " ", "NormalFloat" },
  { " ", "NormalFloat" },
  { " ", "NormalFloat" },
  { " ", "NormalFloat" },
  { " ", "NormalFloat" },
  { " ", "NormalFloat" },
  { " ", "NormalFloat" },
  { " ", "NormalFloat" },
} or {
  { "", "" },
  { "", "" },
  { "", "" },

}
