Opening Options from Pause Menu shouldn't unpause the game

This is just a minor thing but obviously with a huge quality of life improvement: opening the options menu on the pause screen (screenshot below) while in game should not unpause the game. This would allow changing graphics or sounds settings without the worry of being overrun by monsters.

Current workaround is to open the skilltree instead, as it pauses the game aswell but allows you to change options freely.
