Intermittently the ResizeObserver can cause a ResizeObserver loop limit exceeded error. According to https://stackoverflow.com/a/50387233 this is a benign error, however it can cause e2e test failures because testcafe tracks Javascript errors:
✖ combine two single table reports and reorder them 1) A JavaScript error occurred on "http://localhost:3000/#/report/new-combined/edit". Repeat test actions in the browser and check the console for errors. If you see this error, it means that the tested website caused it. You can fix it or disable tracking JavaScript errors in TestCafe. To do the latter, enable the "--skip-js-errors" option. If this error does not occur, please write a new issue at: "https://github.com/DevExpress/testcafe/issues/new?template=bug-report.md".
