Moving Calendar items between O365 calendars loses the event name

I am using Apple Calendar app (on MacOS, iOS, iPadOS) with calendars at MS Office365. When I move the calendar item from one O365 calendar to the other O365 calendar, the name of the event (subject) is lost (deleted). It works OK with iCloud calendars. And, it works well (even with O365 calendars) on iOS and iPadOS. This is an old issue, at least three years old. I do not know how it behaves with Google calendars or others – not tested.

There is only one workaround - not forget and copy the event name to the clipboard before moving.
