12.0p Calendar dayLanes on event resizing exception "Cannot read property 'getTime' of null" and event vanishes

Hi Isomorphic,

I browsed the showcase. In this sample (v12.0p_2020-03-28, Chromium 80 / Win 10) if you drag-resize an event, you get this JS expection and the event vanishes:

16:12:40.129:MUP9:WARN:Log:TypeError: Cannot read property 'getTime' of null
Stack from error.stack:

Hi Isomorphic,
