Details

VS Code with latest grammar pulled in manually from this repo.

Shows up with Dark+ and Light+ themes (plus others)

Repro

using System;
class Z
{
    static void Main(String[] args)
    {
		await someTask; // highlighted as if someTask were a variable of type await
		await someThing.SomeTask; // highlighted correctly
		await someThing.DoSomething(); // highlighted correctly
    }
}

Await is not correctly colored in some cases:

In the first example, the scoped of await is storage.type.cs instead of keyword.other.await.cs
