Plug-in crashes when being lazy loaded by vim-plug

[entropitor]

Describe the bug Support being lazy loaded by vim-plug

Error detected while processing /Users/jens/.vim/bundle/Ionide-vim/ftplugin/fsharp.vim:
line   14:
E117: Unknown function: fsharp#getServerConfig
line   66:
E121: Undefined variable: g:fsharp#languageserver_command
E15: Invalid expression: g:fsharp#languageserver_command
line   76:
E121: Undefined variable: g:fsharp#automatic_workspace_init
E15: Invalid expression: g:fsharp#automatic_workspace_init
Error detected while processing CursorMoved Autocommands for "*.fsx":
E117: Unknown function: fsharp#OnCursorMove

To Reproduce Use vim-plug with the following config:

Plug 'autozimu/LanguageClient-neovim', {
    \ 'branch': 'next',
    \ 'for': 'fsharp',
    \ 'tag': '0.1.155',
    \ 'do': 'bash install.sh',
    \ }
Plug 'ionide/Ionide-vim', {
    \ 'for': 'fsharp',
    \ 'do':  'make fsautocomplete',
    \ }

Expected behaviour The plugin working like normal

Can you provide

• the version of (neo)vim you are using and
• the full vimrc or the minimal vimrc that reproduces the bug?

I tried adding \ 'for': 'fsharp' to both but I couldn't reproduce it with my environment.

Hmm, weird. My vimrc are at

Ah @cannorin, it works in my dotfiles because I have this plugin loaded twice, but if you remove vim-polyglot / add fsharp to the list here https://github.com/entropitor/dotfiles/blob/master/vimrc.bundles#L382, it stops working

[cannorin]

I'm closing this because I believe this problem is fixed somewhere in the past. The following .vimrc works without any problem:
