List automatically scroll to end when delete top_layer object

What MCU/Processor/Board and compiler are you using?

Linux PC simulator using SDL

What LVGL version are you using?

v8.3.10

What do you want to achieve?

List should not scroll automatically when top_layer object deleted

What have you tried so far?

Code to reproduce.

The below code will execute when cancel button pressed

lv_obj_add_event_cb(cancel_btn, top_layer_close_event_cb, LV_EVENT_CLICKED, text_popup_scr);

static void top_layer_close_event_cb(lv_event_t *e)
{
    lv_event_code_t code = lv_event_get_code(e);
    lv_obj_t *top_layer_scr = lv_event_get_user_data(e);

    if (LV_EVENT_CLICKED == code)
    {   
        lv_obj_clear_flag(lv_layer_top(), LV_OBJ_FLAG_CLICKABLE);
        lv_obj_set_style_bg_opa(lv_layer_top(), LV_OPA_TRANSP, 0);
        lv_obj_del(top_layer_scr);
        lv_obj_del(kb);
        kb = NULL;
    }
}

Hello, have you tried putting the message box on the top layer of the screen? lv_layer_top?

I had a somewhat similar issue some time ago: Lv_roller strange behavior when clearing/adding CLICKABLE flag - #10 by kisvegabor

@Tinus. Yes message box created with lv_layer_top() as parent

Issue is not solved. I tried steps described in @Tinus issue but no luck
