Ccleaner icon is taskbar slow to disappear

Idk if this is something that's normal for Ccleaner, but was curious if anyone else had this problem.

When selecting run ccleaner from the context menu of the recycle bin, the Ccleaner icon in the taskbar lingers after the cleaning is done. It stays for about 5-10 seconds longer, not blinking like it would if it was clearning.

That's actually rather normal for many programs in Windows going back eons. Some are more annoying however and won't disappear until the user hovers the mouse over the icon.
