For following input:

Playground Link

const foo = () => (args) => class A {};
new (foo()`bar`)();

The printed code mistakenly drops parentheses around foo()`bar`:

// (Printed)
const foo = () => (args) => class A {};
new foo()`bar`();

...which will change the semantic since () after foo immediately ends NewExpression.

This bug was first observed from SvelteJS' compiler and we'd discovered same issue for a bunch of transpiler including Babel, oxc, SWC, and more.
