BreakoutProcess for Security Hardened Sandbox

[ghost]

Does it make sense? It is even possible?

I would love to have ability to run Potplayer (installed outside of SBIE) by firefox.exe running inside Security Hardened Sandbox using the following extension. https://addons.mozilla.org/en-US/firefox/addon/potplayer-youtube-shortcut/

For Standard Isolation Sandbox trace log shows potplayer is executed via rundll32.exe. For Security Hardened Sandbox rundll32.exe does not even start
