react-tooltip stops working after expanding event list in Full-calendar.

[tutorplanner-web]

I am using react-tooltip @fullcalendar/react. It works fine when I click on an event. But after expanding the events, it doesn't work. Here is the reproducible codesandbox. https://codesandbox.io/s/fullcalendar-daygrid-with-react-tooltip-qrv6l7 As you can see, on clicking "Event 001" the tooltip becomes visible. But if we click on "+4 more" button, the tooltip will not work anymore. If anyone knows how to fix this issue please help. Thank you.
