Global errors differ depending on initial state of playground

[DanielRosenwasser]

I'm having a hard time consistently reproing this, so bare with me.

First, use es2020 as a target.

Playground for this example:

function foo() {
    await using asd = 123;
}

Playground for this example:

function foo() {
    //await using asd = 123;
}

In both cases, toggle a comment on the line in foo, and then toggle the comment state again.

Depending on the initial contents of the playground, the following errors will not reappear:

Cannot find global type 'AsyncDisposable'.(2318)
Cannot find global type 'Disposable'.(2318)

What's more, if you try applying a quick fix on the await keyword to add the async keyword to the function you may get different results than if you enter it manually.

That would be “bear”. I don’t think anyone wants to do the former. 🚎 😉
