Panic when removing default icon

[Henrique194]

Describe the bug

When trying to disable the default icon used by eframe, the application panics. The following code uses the confirm exit example, with the difference it tries to disable the default icon:

#![cfg_attr(not(debug_assertions), windows_subsystem = "windows")] // hide console window on Windows in release

use eframe::egui;
use eframe::egui::IconData;

fn main() -> Result<(), eframe::Error> {
    let options = eframe::NativeOptions {
        viewport: egui::ViewportBuilder::default().with_inner_size([320.0, 240.0]).with_icon(IconData::default()),
        ..Default::default()
    };
    eframe::run_native(
        "Confirm exit",
        options,
        Box::new(|_cc| Box::<MyApp>::default()),
    )
}

#[derive(Default)]
struct MyApp {
    show_confirmation_dialog: bool,
    allowed_to_close: bool,
}

impl eframe::App for MyApp {
    fn update(&mut self, ctx: &egui::Context, _frame: &mut eframe::Frame) {
        egui::CentralPanel::default().show(ctx, |ui| {
            ui.heading("Try to close the window");
        });

        if ctx.input(|i| i.viewport().close_requested()) {
            if self.allowed_to_close {
                // do nothing - we will close
            } else {
                ctx.send_viewport_cmd(egui::ViewportCommand::CancelClose);
                self.show_confirmation_dialog = true;
            }
        }

        if self.show_confirmation_dialog {
            egui::Window::new("Do you want to quit?")
                .collapsible(false)
                .resizable(false)
                .show(ctx, |ui| {
                    ui.horizontal(|ui| {
                        if ui.button("No").clicked() {
                            self.show_confirmation_dialog = false;
                            self.allowed_to_close = false;
                        }

                        if ui.button("Yes").clicked() {
                            self.show_confirmation_dialog = false;
                            self.allowed_to_close = true;
                            ui.ctx().send_viewport_cmd(egui::ViewportCommand::Close);
                        }
                    });
                });
        }
    }
}

Note with_icon(IconData::default()) at the end of the ViewportBuilder creation. Here is the full stack trace of the error:

To Reproduce
Steps to reproduce the behavior:

1. Get example code
2. Add with_icon(IconData::default()) in the viewport creation
3. Build and run application

Expected behavior

The window created should not use any icon.
