Custom grammar's scopes not showing?

[joshpeng]

Per microsoft/vscode#17933 (comment)

In VSC 1.8.1, when I use my custom JavaScript grammar on .jsx file, it doesn't show the custom grammar's scope. It seems to prefer displaying the default VSC grammar scopes.

1. Install Sublime Babel
2. Make sure the language selected is "JavaScript React (Babel)" and then try this line in a jsx file.

console.log(`Running a GraphQL API server at http://localhost:${port}${baseUrl}`)

3. When you hover over localhost the scopes shown are:

source.js
string.template.js

4. If you look in F1 Dev Tools though, the classes are this:
   <span class="token js meta group braces round string interpolated detected-link">http://localhost:</span>
