Duplicate pairs when autocomplete menu is open

[mike-lloyd03]

I'm getting duplicate pairs in Vim 8.1.2292. This seems to only appear when an autocomplete suggestion menu is open.

Plugin list:

• coc.vim
• Vim-Jinja2-Syntax
• vim-polyglot
• sensible
• vim-commentary
• vim-surround
• nerdtree

Try other vim plugins for parirs, I can't reproduce so don't know the reason.
