commit https://github.com/vim/vim/commit/00672e1d3f59dbff91a18d418b2984be96f89ee5 Author: Bram Moolenaar <Bram@vim.org> Date: Sun Jun 26 18:38:13 2016 +0200 patch 7.4.1961 Problem: When 'insertmode' is reset while doing completion the popup menu remains even though Vim is in Normal mode. Solution: Ignore stop_insert_mode when the popup menu is visible. Don't set stop_insert_mode when 'insertmode' was already off. (Christian Brabandt)
