Recurring event with specific StartDate and RULE causes blank schedule

I have a problem the Schedule component, tested in several version including latest ( When I use a particular StartDate for a recurring event, that have a specific rule, nothing is rendered.

  • StartDate: March 31. 2022

That is, I have a recurring event starting from March 31. 2022, on the first Thursday of April every year.

This is an actual setup that can occur, so I need to find a fix for it. The Schedule does not log any errors, but no events - at all - are displayed when this recurring event is in the datasource.

If I change the StartDate to any other valid date it seems to work, OR if I change the BYMONTH value in the rule from 4 to something else it also seems to work and events are rendered.

I've setup a test environment in the link below where the problem can be seen.

Set the 'useErrDate' to true, and the problematic StartDate is used and nothing is rendered in the Schedule.
