Hiding UI completly blacks out main menu

[jakeo]

I was admiring my factory with the Hide UI shortcut (ctrl + shift + F4), and I left the game and looked at the main menu and tried the same shortcut. It sent the entire screen black and also muted some game audio. I think that it would make more sense to just hide the menu but leave the game simulations running, although it may be unfeasible to classify the menu simulations as non-UI

Steps to reproduce:
1) Boot up the game on Windows 11
2) Press ctrl + shift + F4 to hide UI
3) screen goes black and some sound elements are muted
