u already added this topic at 406 line seems here we need topicSettingsTab.waitUntilScreenReady(); can't we openDotMenu from here? extra indent seems we can set it to private w/o @Step, because we'll have only two methods using current inside this class Removed. Fixed. Fixed. Fixed. Fixed. not sure not sure Fixed for sure.
[e2e] Checking Topics settings to make sure retention.bytes is right according to Max size on disk in GB selected value
