It determines if the scrollbar should be shown by assessing its own state and the visibility of the containing workspace. The method's logic doesn't rely solely on the workspace's parent-child DOM relationship for visibility decisions. It takes no arguments and returns nothing (void). The method's core function is to synchronize the scrollbar's display state with the workspace's current state.\n"]]
