Setting sources for multiple filetype buffers

[roylez]

Problems summary

I use multiple filetype markdown.vim-edit for some ad-hot editing, I can set deoplete sources for markdown, or for vim-edit, but sources for markdown.vim-edit defaults to what is set for _.

Expected

muti filetype buffers should have sources inherited from every types

Environment Information

• deoplete version (SHA1): aa32bd

• OS: macOS Big Sur

• neovim/Vim :version output:

  VIM - Vi IMproved 8.2 (2019 Dec 12, compiled Dec 19 2020 21:23:05)

Provide a minimal init.vim/vimrc with less than 50 lines (Required!)

call deoplete#custom#option({
            \'sources': {
            \'_': ['buffer'],
            \'markdown': ['buffer', 'dictionary'],
            \'vim-edit': ['buffer', 'dictionary']})

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

1. Start with the above configuration. Open a markdown file, buffer and dictionary completion should be both there. set ft=markdown.vim-edit, and dictionary completion will be gone.

2. add 'markdown.vim-edit': ['buffer', 'dictionary'] to configuration, and reopen the file, dictionary completion will be available.
