Import path quick suggestions - jsconfig aliases not recognised

[mudrz]

• VSCode Version: 1.17.0
• OS Version: macOS High Sierra 10.13

Reproduces without extensions: Yes

Doesn't work properly with aliases added in jsconfig.json https://code.visualstudio.com/docs/languages/jsconfig

Sample jsconfig.json

{
  "compilerOptions": {
    "baseUrl": ".",
    "paths": {
      "ClientApp/*": ["./ClientApp/*"]
    }
  }
}

Expected behaviour

import Something from 'ClientApp/...'

will pull path intellisense for folder ClientApp

Existing extension path-intellisense for example can also be configured with aliases in settings.json

"path-intellisense.mappings": {
    "ClientApp": "${workspaceRoot}/MvcProject/ClientApp",
  }
