patch 8.2.1727: a popup created with "cursorline" will ignore "firstline"

Commit: https://github.com/vim/vim/commit/99ca9c4868bb1669706b9e3de9a9218bd11cc459
Author: Bram Moolenaar <Bram@vim.org>

    patch 8.2.1727: a popup created with "cursorline" will ignore "firstline"

    Problem:    A popup created with "cursorline" will ignore "firstline".
    Solution:   When both "cursorline" and "firstline" are present put the cursor
                on "firstline". (closes #7000)  Add the "winid" argument to
                getcurpos().
