Objo Studio shows a generic taskbar icon on Linux

After installing Objo Studio on Linux using the Debian package, the application menu shows the correct Objo icon, but the running application shows a generic icon in the taskbar.

The running application should use the Objo Studio icon consistently in the taskbar and application switcher, and should associate correctly with its application-menu launcher.

Follow-up reports indicate that applications built with Objo also show the wrong taskbar icon. Studio's running taskbar entry additionally lacks the Pin option available for other applications. Studio and built applications should display their appropriate icons and support normal launcher association and pinning on desktops that provide those features.
