No errors appear in the console. But I recorded a video for reference.
This happens on chrome, firefox and safari. On mobile safari it doesn’t happen.
Your video link is broken!
Excuse me, I didn’t quite understand that. Indeed, you’re right: when clicking on a date in the calendar, the event creation modal opens, but with the “Do you want to abandon?” button. Yes, indeed, there’s a little bug

For your information, I’ve added a “+ More Info” button for my users who don’t think to click the title to access the topic. I borrowed the idea from @nathank’s “Add to Calendar” button.
Place the script in a theme component under the General /head section.
