Created attachment 1822110 [details] Screenshot It looks like we're occasionally seeing an error with ResizeObserver in CI on the CSV details page. This could be related to https://github.com/openshift/console/pull/9929. https://search.ci.openshift.org/?search=Cannot+read+property+%27firstChild%27&maxAge=48h&context=1&type=bug%2Bjunit&name=&excludeName=&maxMatches=5&maxBytes=20971520&groupBy=job AssertionError: unhandled error: Uncaught TypeError: Cannot read property 'firstChild' of null TypeError: Cannot read property 'firstChild' of null at ResizeObserver.<anonymous> (https://console-openshift-console.apps.ci-op-iw0iz331-75d12.**********************/static/operator-hub-chunk-c762bf09078f229b2014.min.js:1:105875): expected false to be true One failure: https://prow.ci.openshift.org/view/gs/origin-ci-test/pr-logs/pull/batch/pull-ci-openshift-console-master-e2e-gcp-console/1436011339775479808
