Describe the bug
Error using default Coc functionality that appears to be related to new floating window feature

To Reproduce
Steps to reproduce the behavior:

1. Download master branch of neovim
2. Install latest coc.nvim
3. Ensure floating window support is enabled echo exists('##MenuPopupChanged') && exists('*nvim_open_win') should return 1
4. Open .ts file and see error [vim-node-coc]: error on create floating window:request nvim_open_win - Wrong number of arguments: expecting 3 but got 5 when autocomplete tries to occur

Screenshots

[iamcco]

update coc, it's fixed.

[ctaylo21]

@iamcco Ah yes, I see that #539 was intended to fix it. I still see the error, however. I have updated my coc.nvim installation to the latest (including see the above commit in the git history), and I've ran :CocUpdate. What else do I need to do?

[insidewhy]

@ctaylo21 That's because the fix hasn't been released in an official version yet, you can install the latest code by changing your nvim/init.vim:

Plug 'neoclide/coc.nvim', { 'do': 'yarn install' }

Finally had a chance to validate that doing the yarn install version worked. Thanks!
