The current config for it is causing its width and height to be 0.
Also the height:100% on its parent element (".ExpList") is causing the last item within the scrolling area to be cut off. It looks like you tried adding bottom padding to fix that, but it doesn't always work. Once you remove the autosizer and set neither a height nor min-height on its ".ExpList", add "flex-grow: 7" to the rule and Flex will handle the height for you.
Thanks for making a great tool (and hosting it on Github).
P.S. If you need any help with CSS, please feel free to ask me.
