Subject: [PATCH] Fix setting SysTrayIcon visible after explicitly hiding it
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After hiding the QSystemTrayIcon explicitly with .setVisible(false)
resetting visibility with .setVisible(true) does not generate NIM_MODIFY
message and thus preventing the tray icon from being visible again.

Fixes: QTBUG-118133
Pick-to: 6.5
Change-Id: Ic2b1d0f293c92fec7ec697b2fe3d1da9fd0d0e44
