WM_Class 被忽略并且 运行 应用程序的图标未与 docked/favorite 应用程序图标结合
WM_Class ignored and icons of running app doesn't combine with docked/favorite app icon
在我的 Ubuntu 18.04 上，我有这个桌面文件：
$ cat gnome-connection-manager.desktop
[Desktop Entry]
Version=1.0
Encoding=UTF-8
Name=Gnome Connection Manager
Comment=A simple ssh connection manager for gnome
GenericName=Connection Manager
Exec=python3 /opt/gnome-connection-manager-1.2.1/gnome_connection_manager.py
Terminal=false
Type=Application
Icon=/opt/gnome-connection-manager-1.2.1/icon.png
Categories=GTK;GNOME;Network;
Name[en]=Gnome Connection Manager
StartupWMClass=[gnome_connection_manager.py]
我这样放Exec，因为它需要python3，我不能只放脚本，它不会启动。
而且，现在，我将此应用程序固定在我的 dash/taskbar 上的收藏夹中，并且在启动时，它不会将 运行 应用程序图标与停靠的应用程序图标组合在一起。
当我 xprop 并单击 运行 应用 window 时，我可以看到这一行：
WM_CLASS(STRING) = "gnome_connection_manager.py", "Gnome_connection_manager.py"
如果我已经将 WM_CLASS 属性 放在桌面文件中，为什么它不合并图标？
我正在使用 gnome。
