adjusting duration or moving event via the timeline change the event time to "undefined"

[lilygthb]

What happened?

adjusting the length graphically works fine only adjusting from the end of event, moving the event or adjusting the start causes the problem:

What did you expect to happen?

I expected the same behavior for all there ways to adjust the event graphically.

How can we reproduce it (as minimally and precisely as possible)?

set an event then try to adjust the duration from the event start time, or try to move. see attachment

Anything else we need to know?
