Assertion failure when move-to-file code contains entities from ambient module

[DanielRosenwasser]

// @filename: src/globals.ts
declare module "ambient" {
    export interface Thing {}
}

// @filename: src/yadda.ts
import type * as ambient from "ambient";

export class Yadda {
  foo(): ambient.Thing {
    throw new Error("not implemented");
  }

  bar(): ambient.DoesNotExist {
    throw new Error("not implemented");
  }
}

// @filename: src/tsconfig.json
{
    "compilerOptions": {
        "moduleResolution": "bundler",
        "target": "esnext",
        "strict": true,
        "outDir": "dist"
    },
    "include": [
        "src"
    ]
}

Move to a new file on Yadda, and the following assertion error is issued from TSServer
