Inconsistent event firing of beforeEventSelectionChange and eventSelectionChange

Hello, I found this topic which seems relevant to my issue.

What I would expect is that events fired in [b]beforeEventSelectionChange[/b] will be duplicated in [b]eventSelectionChange[/b] but from my testing the following happens:
[list]On first event selection: [b]beforeEventSelectionChange[/b] is fired with [b]clear[/b] action and [b]eventSelectionChange[/b] is fired with [b]select[/b] action [attachment=2]1.png[/attachment][/list]
[list]Then on empty scheduler click: [b]beforeEventSelectionChange[/b] is fired with [b]update[/b] action and [b]eventSelectionChange[/b] is fired with [b]clear[/b] action [attachment=1]2.png[/attachment][/list]
[list]Then another click on empty scheduler: [b]beforeEventSelectionChange[/b] is fired with [b]clear[/b] action and [b]eventSelectionChange[/b] is not fired [attachment=0]3.png[/attachment][/list]

Is this behavior expected by design?
