While playing with this, I discovered that drag-dropping event will read the UTC time as local time. (Shiftted 8 hours earily in my environment). For example, if I drag an event and drop it at 10:00 AM, it will appear at 2:00 AM:

dragging non-extension managed calendars works fine, and maually editing time works fine too. Thunderbird version: 102.11.2

The simple properties API is being removed in favor of jcal in #34 . If you use jcal, your timezone calculations should be correct.
