Salesforce Full Calendar Tooltip создается, но не отображается

Question

У меня есть компонент ауры, который отображает полный вид временной шкалы календаря, и я пытаюсь отобразить всплывающую подсказку, используя popper и tooltip. js. Как видно из изображения консоли браузера, всплывающая подсказка создается при вводе мыши, но не отображается.

Скрипты из компонента

   <ltng:require scripts="{!join(',',
                       $Resource.FullCalendarCoreMainV4_3_1JS, 
                       $Resource.FullCalendarMomentMainV4_3_1JS,
                       $Resource.FullCalendarTimelineMainV4_3_1JS,
                       $Resource.FullCalendarResourceCommonMainV4_3_1JS,
                       $Resource.FullCalendarResourceTimelineMainV4_3_1JS,
                       $Resource.PopperMin, 
                       $Resource.TooltipMin
                       )}"
             styles="{!join(',',
                      $Resource.FullCalendarCoreMainV4_3_1CSS,
                      $Resource.FullCalendarTimelineMainV4_3_1CSS,
