[Typescript] bug -- backticks sometimes results in the rest of the file being highlighted as a string

[williamstein]

Here is a minimal .ts example to reproduce the problem:

class Foo {
  f(obj) {
    for (let key in obj) {
    }
  }

  g(a: string): void {
    if (!this.h(a)) {
      throw Error(`${a}`);
    }
  }

  // This should not be red!
  h(a: string): boolean {
    //...
  }
}

Paste that into the official demo and you'll see:

I refined the one above to be a bit shorter. It seems to trip over nested { { .. } }:

if (true) {
  for (let i in [1, 2, 3]) {
    console.log(`${i}`);
  }
}
console.log("this is all orange");
console.log("this is all orange");
console.log("this is all orange");

Seems this is still an issue alexcanessa/typescript-coverage-report#61 (comment)

That's a different issue -- the mode didn't support the newly introduced template string types yet. Attached patch should address that.
