Issue Type: Bug

Reproduction code:

"use strict";
try {
    throw new Error();
} catch        {
    console.info("Hello world");
}

Expected behaviour:
When vscode tried formatting the code, the extra spaces should be removed.

What happend:
The extra spaces can not be removed via formatting. (But when I put () in spaces, formatter can format the code properly.)
Does this issue occur when all extensions are disabled?: Yes
Does this issue occur on Insider build?: Yes

My vscode setting:
"editor.defaultFormatter": null

Hmmm, IDK why this issue had been transferred to TypeScript, can anyone explain it please?
