Describe the bug

The bug happens when you select one autocomplete option and the documentation tooltip appears. This disables completely current snippet placeholders, making it unusable.

I suspect the problem happens due to the new buffer created for the documentation.

To Reproduce

vimrc

call plug#begin('~/.config/nvim/plugged')

Plug 'SirVer/ultisnips'
Plug 'hrsh7th/nvim-compe'

call plug#end()

set completeopt=menuone,noselect

let g:compe = {}
let g:compe.enabled = v:true
let g:compe.autocomplete = v:true
let g:compe.min_length = 1
let g:compe.preselect = v:false

let g:compe.source = {}
let g:compe.source.path = v:true
let g:compe.source.buffer = v:true
let g:compe.source.ultisnips = v:true

1. Expand an Ultisnips snippet with multiple placeholders.
2. Write something to show the autocomplete options and select one option that displays documentation.

Note: It works correctly when documentation is false.

let g:compe.documentation = v:false

Actual behavior

You're unable to jump to the next placeholder, making Ultisnips basically useless.

Expected behavior

It should jump correctly between placeholders.

Hm... I can't reproduce it.

It happens after the snippet is expanded. For example, when you are inside href="|", select an autocomplete option that shows documentation (like another snippet or lsp function).

Also... I'm starting to think that this could be a Ultisnips bug. After disabling the documentation, I have another plugin that shows a popup and breaks the placeholder jump too. Still, please take a look. I would like to get your opinion about it. Thanks.

Probably, I found the reason. It caused by Ultisnips#ExpandSnippet. If current activated snippet can jumpable, the function would not effect anymore.

I think we can close this... Not a simple solution for now it seems. I found this one on Ultisnips SirVer/ultisnips#1188
