mount goes Out of Memory

Component: https://github.com/dowjones/react-dropdown-tree-select/blob/perf-tweaks/src/tree/index.js

Test: https://github.com/dowjones/react-dropdown-tree-select/blob/perf-tweaks/src/tree/index.test.js#L48

Branch with repro: https://github.com/dowjones/react-dropdown-tree-select/tree/perf-tweaks

React has no issues with it. Test pages (yarn demo) works fine on Chrome, Edge browsers with no issues. Only mount fails.

This test started failing after adding react-infinite-scroll-component. However, I'm not sure why. I've checked their source code and nothing stands out of the ordinary. If I take out the component, test runs fine.

Current behavior

mount(<Tree data={treeManager.tree} />) throws Out of Memory error.

Expected behavior

Should not throw Out of memory error.
