In T375287, a change was made that is riding next week's train (deployed to all wikis by 20th) that updates how Codex styles are loaded. There is a small risk that this may result in unstyled message boxes on certain pages. If you see any issues please report them on this user notice. User generated content (e.g. templates) is not impacted. Gadgets may be impacted.
What to do if you see any issue.
- If a gadget is broken you can fix this by adding mediawiki.codex.messagebox.styles to the gadget dependencies
- If the issue is present on a special page or action page please report it here so that we can file a ticket and route the bug to the appropriate maintainer.
Example
If a warning looks unstyled as in the example below (please do not report incorrect colors or positioning of the message) please check the HTML of the page. If the HTML contains <div class="cdx-message you have found a bug.
How it should look:
