[Feature request] Pause the game on when the application window loses focus

As the title says, the game continues to play even if the game loses focus to another window or the desktop.

In my case, apps in Windows 11 sometimes take the focus away with a popup or dialog and this automatically leads to character death and massive XP loss.

It would be nice if the game pauses when this happens given all the punishment mechanics in-game.

Thanks.
