About the behavior of openFilterWindow when using autocmd and keymap

[yasunori0418]

Problems summary

The behavior is different when opening the filter manually and when opening the filter with autocmd.

Expected

There are the following differences when running openFilterWindow with autocmd and when running openFilterWindow manually using the configured keymap.

• autocmd
  • The list of items will not be updated until you confirm what you entered in the cmdline.
• keymap
  • The list of items is updated to sync with the input in cmdline

I would like to unify the behavior with keymap or autocmd. Ideally, the behavior when using keymap is the best, but as far as I have checked the specifications, I think that the behavior when using autocmd is the expected behavior.

Provide a minimal init.vim/vimrc without plugin managers (Required!)

const s:repo_path = expand("~/.cache/dpp/repos/github.com")
const s:plugins = [
  \ 'Shougo/ddu.vim',
  \ 'Shougo/ddu-ui-ff',

command! Test call ddu#start(#{sources: ['file_rec']})

How to reproduce the problem from neovim/Vim startup (Required!)

• Vim
  1. vim -N -u .vimrc
  2. :Test
  3. Enter something from there to search
     • At this time, it will not synchronize with the input and the item list will not be updated until the input is confirmed.
  4. Comment out the autocmd that automatically opens openFilterWindow with Ddu:uiDone
  5. One more steps 1 to 2.
  6. Run openFilterWindow with i by keymap
     • At this time, the item list will be updated in sync with the input.
• neovim
  1. nvim -u .vimrc
  2. Perform the same operations 2 to 6 as in Vim and the same behavior will occur

Reproduced...

[Shougo]

autocmd User Ddu:uiDone ++nested
  \ call ddu#ui#do_action("openFilterWindow")

It must be async_action().
