This avoids work being done when it doesn't need to be. For instance, the preview generator waits for everything to have settled using a 200ms timer before generating a preview. This timer fired also in response to onStyleOptionChanged and needlessly delayed preview generation when navigating between folders despite the style option (e.g. icon size, view mode) not having changed.
