Original GitHub issue: https://github.com/modoboa/modoboa/issues/2555

Impacted versions

OS Type: Ubuntu
OS Version: 20.4.4 (Focal Fossa)
Database Type: PostgreSQL
Database version: 12 (default)
Modoboa: 2.0.1
installer used: Yes
Webserver: Nginx

Steps to reproduce

login with simple user (or any other) and go to webmail
create a simple calendar event
use mouse to drag and drop the event to other time of the same day or another day, or change its duration by dragging and dropping the border of the event

Current behavior

Visually the event looks correct for the first time. The UI even says that the event was successfully updated.

BUT - when the view is refreshed (eg by going back and forth for dates), the event changes to "one hour". Effectively it is zero length event as the end time is the same as the start time.

When doing the same in another calendar client (such as macOS Calendar), everything works fine.

Expected behavior

I am expecting that the start and end times change accordingly.
For moving - the start and end dates and times can change but not the duration
For resizing - the start date and time remains the same and only the end date and time together with the duration should change

Video/Screenshot link (optional)

Can provide but it is so simple to reproduce, that it is not needed. ;)
