Calling startTouchGesture() on the workspacesViews can change the visibility of the workspaces if not all of them are already shown, such as when there are more than 3 workspaces or for 3 workspaces if we are not on the central one. This invalidates the allocation and the width used as distance for the gesture would become 0, resulting in drag gestures immediately jumping to the first or last workspace due to a division by 0.
