Cursor jumps into floating window of function signature help

[loshjawrence]

My testing minimal init.vim

call plug#begin('~/.vim/bundle')
    Plug 'neovim/nvim-lspconfig'
    Plug 'nvim-lua/completion-nvim'
call plug#end()
inoremap <expr> <Tab>   pumvisible() ? "\<C-n>" : "\<Tab>"
inoremap <expr> <S-Tab> pumvisible() ? "\<C-p>" : "\<S-Tab>"
lua require'lspconfig'.tsserver.setup{on_attach=require'completion'.on_attach}
au Filetype javascript setl omnifunc=v:lua.vim.lsp.omnifunc
set completeopt=menuone,noinsert,noselect

How to reproduce

1. Get the function signature help to pop up by typing some params in a function call site.
2. Sometimes cursor will window jump into the floating window. for me its >50% of the time so it makes function signature help unusable.
3. Can try to brute force trigger by holding , or holding delete on a long string of ,

Expected behavior The cursor should not jump into the floating window of the function signature help.

Closing as this seems to be a neovim issue.

This is not a neovim issue, but a completion.nvim issue
