Events longer than 24h cannot be dragged over a specific timeslot in Scheduler timeline view

[IvanDanchev]

Bug report

Regression introduced in R3 2020 SP2. Possibly related to #6034

Reproduction of the problem

Dojo example.

1. Attempt to drag first event to a slot before the one it starts in.

Current behavior

The event cannot be dragged/dropped over the desired slot. It is automatically placed over the first slot of the day it starts in.

Expected/desired behavior

The event can be dropped over the desired time slot.

Environment

• Kendo UI version: 2021.1.224
• jQuery version: x.y
• Browser: [all]

#6034 becomes reproducible again after the fix.

1. Open scheduler/timeline demo
2. Make the evaluations event an All day event
3. Drag it to other resource
4. Open the edit form
   Actual: The allday checkbox is NOT checked

Edit: When dragging the all day event it should be possible to change the time when dragging horizontally. In this scenario the event becomes a non-all day event and it is expected that the alldat checkbox is unchecked.
