Assertion in JSX spread causes missing newline in JS output

Steps to reproduce

const c = <EntryTextDialog
    {...{
        first: 0,
        foo: 1,
        bar: 2 as any,
        baz: 3,
        last: 4
    }}
/>

const c = _jsx(EntryTextDialog, { first: 0,
    foo: 1,
    bar: 2,
    baz: 3,
    last: 4 });

Newlines are removed before and after the property with the assertion (not others)

const c = _jsx(EntryTextDialog, { first: 0,
    foo: 1, bar: 2, baz: 3,
    last: 4 });
