ComboBox setValue sometimes set to null

Flow

I have this code where I populate a ComboBox and try to set the value:

    authenticatedUser.get().ifPresent(owner->{
        deviceService.findAllByOwner(owner, true)
            .collectList()
            .subscribe(devices->{
                System.out.println(devices);
                ui.access(()->{
                    deviceComboBox.setItems(devices);
                    if(!devices.isEmpty()) {
                        System.out.println("Set VALUE");
                        System.out.println(devices.get(0));
                        deviceComboBox.setValue(devices.get(0));
                        System.out.println(deviceComboBox.getValue());
                    }
                });
            });
    });

The printout always work where the getValue prints the actuall set item, but the value in the ComboBox is set to null 50%-ish of the time, I check this with a button, also the ComboBox don’t display anything. I have no other places in my code where the setValue is used (belive me, I have searched…)

If I changed the component to a Select the setValue is consistently set.

I am on Vaadin 24.4.11. Is there a know issue on the ComboBox or is it something I don’t understand?

If I remember correctly… I’ve seen a similar report because of the asynchronous usage with push - remove it and it should work 100% of the time
