How to reproduce the issue

1. Enter the files
2. Sign numbers apear

I use CoC nvim with this config for ufo
`
vim.wo.foldcolumn = '1'
vim.wo.foldlevel = 99 -- feel free to decrease the value
vim.wo.foldenable = true

local handler = function(virtText, lnum, endLnum, width, truncate)
local newVirtText = {}
local suffix = ('  %d '):format(endLnum - lnum)
local sufWidth = vim.fn.strdisplaywidth(suffix)
local targetWidth = width - sufWidth
local curWidth = 0
for _, chunk in ipairs(virtText) do
local chunkText = chunk[1]
local chunkWidth = vim.fn.strdisplaywidth(chunkText)
if targetWidth > curWidth + chunkWidth then
table.insert(newVirtText, chunk)
else
chunkText = truncate(chunkText, targetWidth - curWidth)
local hlGroup = chunk[2]
table.insert(newVirtText, { chunkText, hlGroup })
chunkWidth = vim.fn.strdisplaywidth(chunkText)
-- str width returned from truncate() may less than 2nd argument, need padding
if curWidth + chunkWidth < targetWidth then
suffix = suffix .. (' '):rep(targetWidth - curWidth - chunkWidth)
end
break
end
curWidth = curWidth + chunkWidth
end
table.insert(newVirtText, { suffix, 'MoreMsg' })
return newVirtText
end

-- global handler
require('ufo').setup({
fold_virt_text_handler = handler
})
