Undo system tray bug workaround
In KF5 KStatusNotifierIcon would show/hide the main QWindow whilst in KTorrent we would show/hide the main QWidget. A bug in Qt6 meant that hiding/showing the QWindow did not neccessarily hide the QWidget.
So if a user closed the window to the tray, the QWidget was considered hidden but the QWindow was not. Then when clicking on the tray icon, the QWindow visiblity was being toggled but the QWidget visibility was always hidden.
To work around this we changed KTorrent to hide the QWindow instead of the QWidget. Now KStatusNotifierIcon has been updated to hide the main QWidget instead of the QWindow, so we must undo the changes made here.
The upstream bug should fixed in Qt 6.7 anyway.
