fakeAsync lines are not breaking when width bigger than Print Width

[tspmelo]

Prettier 1.14.3
Playground link

--parser babylon

Input:

  it(
    'should run postProcess and split the breadcrumbs when navigating to hosts',
    fakeAsync(() => {
      expect(1).toEqual(1);
    })
  );

Output:

it("should run postProcess and split the breadcrumbs when navigating to hosts", fakeAsync(() => {
  expect(1).toEqual(1);
}));

Expected behavior:
1st line is longer than 80 cols so it should break.

This change was introduced in #4954.
I prefer the new fakeAsync formatting, but I think print width should have priority.
