Can't see cursor when using winblend in telescope

[dlvhdr]

Description

When I use some low value for winblend, I can BARELY see my cursor if it's on a space (meaning, not under a character). I'm using alacritty with the folke/tokyo-night theme.

Neovim version

NVIM v0.6.1
Build type: Release
LuaJIT 2.1.0-beta3
Compiled by brew@Monterey

Operating system and version

macOS 12.0.1

checkhealth telescope

telescope: require("telescope.health").check()

Steps to reproduce

1. Set telescope config accordingly
2. Maybe use Alacritty (not sure it's necessary)

Expected behavior

Should be able to easily see cursor when not on a character.

Actual behavior

Some images:

Minimal config

require("telescope").setup({
  defaults = {
    winblend = 5,
    path_display = { truncate = 5 },
    get_status_text = function()
      return ""
    end,
    preview = {
      filesize_limit = 3,
      timeout = 250,
    },
    selection_strategy = "reset",
    sorting_strategy = "ascending",
    scroll_strategy = "limit",
    color_devicons = true,
    layout_strategy = "horizontal",
    layout_config = {
      width = 0.95,
      height = 0.85,
      prompt_position = "top",
      horizontal = {
        preview_width = function(_, cols, _)
          return math.floor(cols * 0.4)
        end,
      },

      vertical = {
        width = 0.9,
        height = 0.95,
        preview_height = 0.35,
      },

      flex = {
        horizontal = {
          preview_width = 0.9,
        },
      },
    },
  },
  extensions = {
    fzf = {
      fuzzy = true,
      override_generic_sorter = true,
      override_file_sorter = true,
      case_mode = "smart_case",
    },
  },
})

We could add a TelescopeCursor hl group
