Originally when using the lookup as dropdown component the dropdown would randomly scroll up and down when you hover over the options with the mouse.
This issue comes from the fluentui library and is described here: https://github.com/microsoft/fluentui/issues/8748
I was able to resolve this issue by setting calloutProps={{ calloutMaxHeight: 300 }}
