Incorrect processing of awaited brackets

[charsleysa]

Using the await keyword on the result of code inside brackets produces the wrong output.

Example:

declare const a: boolean;
declare function gl(): Promise<void>;
declare function bg(): Promise<void>;

async () => {
    await (a != true ? gl() : bg());
}

produces

(async () => {
  await a != true ? gl() : bg();
});

Expected:

(async () => {
  await (a != true ? gl() : bg());
});

EDIT: possible related to #1996
