Describe the bug
The "ghost" element that appears when we try to resize an event in the Scheduler is missing in the Timeline and Month views. The result is that the users don't have a visual representation of what is the new size of the event they are modifying. The resizing itself is working correctly. The issue is only with the visual representation.

To Reproduce

1. Open this StackBlitz example
2. From the Views in the upper right corner select "Timeline" or "Month" view
3. Select a random event and try to resize it.

Expected behavior
An element that shows the possible new size of the event should appear like it is in the Day view, for example.
