Turns on/off the flag which suppresses rebuilding of the working set
when the "workingSetSort" event is dispatched from MainViewManager.
Only used while dragging things around in the working set to disable
rebuilding the list while dragging.

@param {boolean} suppress - true suppress, false to allow sort redrawing
