Top-level 'await' is not recognized by extension

I have installed latest Deno extenstion version from VSCode marketplace and everything is ok except the top-level await statements. It seems that extension just does not recognize them:

Output of deno --version command:

❯ deno --version
deno 1.0.0
v8 8.4.300
typescript 3.9.2

VSCode version:

❯ code --version
1.42.1
c47d83b293181d9be64f27ff093689e8e7aed054
x64

OS: macOS Mojave 10.14.6 18G2022 x86_6

I’m seeing ts(1378) instead of ts(1308). Not sure if what I’m getting is directly related to this issue or not.

Top-level 'await' expressions are only allowed when the 'module' option is set to 'esnext' or 'system', and the 'target' option is set to 'es2017' or higher.ts(1378)

Here are the steps I followed:

1. Installed the extension
2. Created .vscode/settings.json with following entry

{
  "deno.enable": true,
  "[typescript]": {
    "editor.defaultFormatter": "denoland.vscode-deno"
  }
}

1. Wrote a basic oak server

import { Application } from "https://deno.land/x/oak/mod.ts";

const app = new Application();

app.use((ctx) => {
  console.log("received request", ctx.request);
  ctx.response.body = "Hello World!";
});

console.log("oak server listening at http://localhost:8000");

await app.listen("127.0.0.1:8000"); // ts(1378) triggering on this line

Here are the version details:

$ deno --version
deno 1.3.0
v8 8.6.334
typescript 3.9.7

VSCode is also using TypeScript v3.9.7

Should be resolved in version 3.x of the extension.
