Handle Leaks with WM_SETTINGCHANGE Message

There is handle leak in Qt whenever there is a Windows message WM_SETTINGCHANGE comes up.

It can be reproduced with attached minimal example, It seems to leak 4 handles per WM_SETTINGSCHANGE for each top level widget for each screen connected. The minimal example leaks 12 handle for each message with 3 screens connected, triggered by a click in the application.
