This prevents blocks from being destroyed before their hotspots are destroyed, in case it is used for a pending click event that fires between the bar receiving a new status, which destroys the block, and the bar rendering the new status, which destroys the hotspot; this problem can be easily produced by scrolling on a block that immediately causes a new status to be sent, with multiple outputs
