Doesn't restore the insert mode after pick or after closing the window

[backdround]

To reproduce:

• Launch the following selection by <M-d> mapping:

local select = function()
  vim.ui.select({ "a", "b", "c" }, {
  }, function()
    -- normal mode here
  end)
end
vim.keymap.set("i", "<M-d>", select)

• Close the selection by <Esc>

The default selection preserves the insert mode.
