MATE does not follow the Desktop Application Autostart Specification

[FreaxMATE]

Expected behaviour

If an application autostarts by having a .desktop file installed in the system wide autostart directory, an individual user can disable the autotomatic start of this application by placing a .desktop file of the same name in its personal autostart directory which contains the key Hidden=true.

Actual behaviour

App starts nonetheless

Steps to reproduce the behaviour

on manjaro create those to files:

kunruh@thinkfreax ~> cat .config/autostart/pamac-tray.desktop
[Desktop Entry]
Name=Update Notifier
Icon=update-notifier
Exec=sh -c "GDK_BACKEND=x11 pamac-tray"
Terminal=false
Type=Application
StartupNotify=false
NotShowIn=KDE;GNOME;
Hidden=ture
kunruh@thinkfreax ~> cat /etc/xdg/autostart/pamac-tray.desktop
[Desktop Entry]
Name=Update Notifier
Icon=update-notifier
Exec=sh -c "GDK_BACKEND=x11 pamac-tray"
Terminal=false
Type=Application
StartupNotify=false
NotShowIn=KDE;GNOME;
kunruh@thinkfreax ~> 

reboot and see the tray start anyway
