This effect is now ran on every render because loadHistory changes every time (useCallbacks are not there just for fun). Eslint is also complaining about missing dependencies

This seems to be run on every render anyway due to virtualizer.getVirtualItems(). Not sure what to do about this, as it's the suggested way to achieve this effect in https://tanstack.com/virtual/latest/docs/framework/react/examples/infinite-scroll, and from what I can see, the actual result of firstItem doesn't change.
