Bug ID: 48404
           Summary: Can't close free game notifications from Epic Games
                    Store
           Product: Wine
           Version: 5.0-rc3
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

How to reproduce:
1) Install Epic Games Store (which can be done easily by using a version of
Lutris installer that doesn't install any native components
https://lutris.net/games/epic-games-store-untainted/installer/edit)
2) Launch it with -opengl -SkipBuildPatchPrereq flags
2) Get a notification about current free game giveaway
3) Click on [X] (close) button
Instead of being closed, the notification instead gets recreated, and after
that, it can't be closed without use of tools like xkill.
