The test only waits 120 seconds so not sure if it updates at all. This test has been quarantined due to this transient bug. Current failure issue: https://gitlab.com/gitlab-org/gitlab/-/issues/346206 ### Steps to reproduce <!-- Describe how one can reproduce the issue - this is very important. Please use an ordered list. --> ### Example Project <!-- If possible, please create an example project here on GitLab.com that exhibits the problematic behavior, and link to it here in the bug report. If you are using an older version of GitLab, this will also determine whether the bug is fixed in a more recent version. --> ### What is the current *bug* behavior? It occasionally takes over 2 minutes for changes to issuable assignees to display those changes in the assignees block. ### What is the expected *correct* behavior? Assignees should update fairly quickly with the real-time update feature. ### Relevant logs and/or screenshots https://gitlab.com/gitlab-org/gitlab-qa-mirror/-/jobs/907310250 Screenshot from the above e2e test that waited 120 seconds:  ### Output of checks <!-- If you are reporting a bug on GitLab.com, write: This bug happens on GitLab.com --> #### Results of GitLab environment info <!-- Input any relevant GitLab environment information if needed. --> <details> <summary>Expand for output related to GitLab environment info</summary> <pre> (For installations with omnibus-gitlab package run and paste the output of: `sudo gitlab-rake gitlab:env:info`) (For installations from source run and paste the output of: `sudo -u git -H bundle exec rake gitlab:env:info RAILS_ENV=production`) </pre> </details> #### Results of GitLab application Check <!-- Input any relevant GitLab application check information if needed. --> <details> <summary>Expand for output related to the GitLab application check</summary> <pre> (For installations with omnibus-gitlab package run and paste the output of: `sudo gitlab-rake gitlab:check SANITIZE=true`) (For installations from source run and paste the output of: `sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production SANITIZE=true`) (we will only investigate if the tests are passing) </pre> </details> ### Possible fixes <!-- If you can, link to the line of code that might be responsible for the problem. -->
