In the Scheduler's Timeline view when there are events with the same Start and End dates and one of them is resized, the Scheduler reorders the events automatically, placing the longest event on top and the shortest event at the bottom of the slot. The same occurs in other views, for example, in the Week view the events are automatically reordered from left to right (longest to shortest).
It would be nice to be able to control this behavior and disable it through a dedicated option.
