Line break missing with indent_style = "Visual"

The following code is formatted as follows with rustfmt 1.4.11-nightly (1838235 2019-12-03) and also rustfmt 2.0.0-rc.1-nightly (facba6a5 2020-01-14):

fn main() {
    let global_manager = GlobalManager::new_with_cb(&display,
                                                    global_filter!([WlSeat,
                                                   2,
                                                   move |seat: Main<WlSeat>, _: DispatchData| {
                                                       let seat_data =
                                                           RefCell::new(SeatData::default());
                                                       seat.as_ref()
                                                           .user_data()
                                                           .set(move || seat_data);
                                                       seat.quick_assign(seat_handler);
                                                       seats_2.borrow_mut().push(seat);
                                                   }]));
}

Looks like it forgets to break the line after =, inserting the line break gives the desired result:

fn main() {
    let global_manager =
        GlobalManager::new_with_cb(&display,
                                   global_filter!([WlSeat,
                                                   2,
                                                   move |seat: Main<WlSeat>, _: DispatchData| {
                                                       let seat_data =
                                                           RefCell::new(SeatData::default());
                                                       seat.as_ref()
                                                           .user_data()
                                                           .set(move || seat_data);
                                                       seat.quick_assign(seat_handler);
                                                       seats_2.borrow_mut().push(seat);
                                                   }]));
}

Reproduce the issue with the provided Rust snippet using rustfmt 1.4.11-nightly or 2.0.0-rc.1-nightly and the Visual indentation style. Trace the formatting path for the assignment and nested function call; done means rustfmt inserts the line break after = and matches the desired output.
