Pausing in superflat void worlds unlike in other certain world types does not include a video screenshot in the world selection menu.

I was pausing the game in superflat void worlds, then clicking the "Save and Quit to Title" button, and then clicking the "Singleplayer" button opening up the world selection menu, but once inside of that menu it doesn't appear to form a screenshot attached to the world I was playing in as which I've paused the screen in that world unlike within other types of worlds.
