Before opening a new issue, make sure to search for keywords in the issues filtered by the "regression" or "type::bug" label: - https://gitlab.com/gitlab-org/gitlab/issues?label_name%5B%5D=regression - https://gitlab.com/gitlab-org/gitlab/issues?label_name%5B%5D=type::bug and verify the issue you're about to submit isn't a duplicate. ---> ### Summary when creating a wiki page in any project, there were two alerts that appeared after successfully being created. <!-- Summarize the bug encountered concisely. --> ### Steps to reproduce 1. click the `new page` button on any wiki page 2. fill in the title and description of the wiki 3. and then click the `create page` button 4. Then the two alerts in the lower left corner are displayed <!-- Describe how one can reproduce the issue - this is very important. Please use an ordered list. --> ### Example Project https://gitlab.com/youngbeomshin/empty_test_project/-/wikis/home or create any new 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? disappear two alerts message after the wiki was created. <!-- Describe what actually happens. --> ### What is the expected _correct_ behavior? the alert was shown only once. <!-- Describe what you should see instead. --> ### Relevant logs and/or screenshots  <!-- Paste any relevant logs - please use code blocks (```) to format console output, logs, and code as it's tough to read otherwise. --> ### Output of checks <!-- If you are reporting a bug on GitLab.com, uncomment below --> <!-- This bug happens on GitLab.com --> <!-- /label ~"reproduced 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. -->
