Should load tsserver from main workspace on restart

[javier-garcia-meteologica]

I work in a main project that uses typescript 4.3. After ocasionally browsing through other projects, coc-nvim accumulates workspaces, as described here. Then if I call :CocRestart, coc-tsserver loads instead the tsserver from another project, which uses typescript 4.0.

coc-tsserver doesn't care which tsserver gets loaded, but in this case it's important. The main project uses typescript 4.3 because it uses rxjs which exports type definitions using package.json#typesVersions and this feature is only supported in typescript 4.2+.

https://github.com/neoclide/coc-tsserver/blob/66ae279b1a3441ad5ca77d47934f99f039cd1e0b/src/server/utils/versionProvider.ts#L109-L121

I've tried to close all buffers from other workspaces and then delete the workspaces in CocList folders, but they still re-appear after :CocRestart. I even tried let g:WorkspaceFolders = [].

• Could coc-tserver start a separate instance of tsserver for each workspace?
• If the same instance has to be shared between many workspaces, could coc-tsserver give preference to a workspace that matches :pwd or to a workspace that matches the path of the file of the current window?
• How can I completely reset coc-nvim environment?

No need for that since tsserver can support multiple folders.

Seems we should prefer workspace folder of current buffer to avoid this issue.
