There was a similar Windows bug when a tooltip in the notification area (systray) wouldn't disappear no matter what. I first found the bug in Windows XP, and then witnessed it in Vista, in Windows 7, Windows 10. It was my ritual to check if it's fixed yet when upgrading to a new version of Windows. It never was. Since then I moved to Linux and now I don't know if it's fixed or not.
