Project root detected incorrectly when opening `tsx` file but not when opening `ts` file

[insidewhy]

Describe the bug

I open a .ts file in my project: nvim src/blah.ts.

[LC] Project root: /home/me/project/client

That's great, project/client is where my tsconfig.json lives and everything is fine. Next I open a tsx file using :tabe src/App.stx and see:

[LC] Project root: /home/me/project.

This is wrong, my project root with my tsconfig.json in is project/client, not project. Sure project is where my .git file is but it's a monorepo with many projects. Given the detected project root does not contain a tsconfig.json everything goes wrong.

Environment

• neovim/vim version (nvim --version or vim --version): v0.3.4
• This plugin version (git rev-parse --short HEAD): 26c8727
• This plugin's binary version (bin/languageclient --version): languageclient 0.1.142

let g:LanguageClient_rootMarkers = {
\ 'typescript.tsx': ['tsconfig.json']
\ }

Added the rootMarkers config, after this the root directory is detected correctly but code completion fails in tsx files (ts files are still working fine). This is probably a bug with javascript-typescript-langserver then?

[insidewhy]

I moved from javascript-typescript-langserver to https://github.com/tomv564/lsp-tsserver and with that code completion works in both ts files and tsx files, but that rootMarkers config above is still needed. So I think maybe it'd be good if LanguageClient-neovim detected the same project root directory for ts files as it does for tsx files.

In case anybody else gets here, it's also worth pointing out that javascript-typescript-langserver isn't a good choice for hardcore ts development because it doesn't work with scoped packages or tsx.
