syntax highlighting failures in TS files

[haraldschilly]

I assume this is a codemirror upstream issue, but I'm still posting this here in case there are more than just me noticing such an issue. The problem is, after a certain point in the .ts file -- I always saw this in conjunction with string interpolation backticks (!) -- all highlighting is gone. Editing plain orange code text is only half the fun 🙈 I'm also wondering if this affects other types of files …

Interference involving combining backticks and dollar signs?

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've created an upstream issue: codemirror/codemirror5#5774

This is now fixed upstream.

that's how it looks in cocalc. closing.
