Code to reproduce

local Input = require("nui.input")
local event = require("nui.utils.autocmd").event

local input = Input({
  relative = "cursor",
  position = {
    row = 0,
    col = 0,
  },
  size = {
    width = 20,
  },
  border = {
    style = "rounded",
    text = {
      top_align = "center",
    },
  },
}, {
  default_value = "Hello",
})

-- mount/open the component
input:mount()

-- unmount component when cursor leaves buffer
input:on(event.BufLeave, function()
  input:unmount()
end)

patch_cursor_position is used when exiting insert mode with <CR> places cursor one character backward. When relative is cursor, the patch_cursor_position function doesn't run due to target_cursor and cursor not relate. https://github.com/MunifTanjim/nui.nvim/blob/cbd2668414331c10039278f558630ed19b93e69b/lua/nui/input/init.lua#L12-L22 In this context, the target_cursor is actually the cursor position of the input prompt not the previous cursor position before open prompt. This commit https://github.com/MunifTanjim/nui.nvim/commit/3dc46d725f7b94bee5117c0a699b57b1902b5d65 I don't know what problem it fixes but revert it works like expected.

Should be fixed now.
