I want to deselect row by clicking on the selected row again. Currently, the https://www.bryntum.com/docs/scheduler/api/Scheduler/view/Scheduler#event-selectionChange event doesn't support that action. I tried to use the https://www.bryntum.com/docs/scheduler/api/Scheduler/view/Scheduler#event-cellClick event (when the row containing clicked cell is selected, I deselect this row), but this event is triggered after https://www.bryntum.com/docs/scheduler/api/Scheduler/view/Scheduler#event-selectionChange event, so when i click on the row it is selected and then deselected immediately.
