Steps to reproduce
- Request a page (and banner) displayed in the Minerva skin (e. g. wmua_wikiscience_2021 banner on enwiki)
- The banner is displayed regardless of any CentralNotice campaign settings.
- No banner is displayed.
- This is severely affecting the fundraising campaign (at the least the one ran by WMDE).
- It doesn't seem to be an issue with any banner. This is happening with all banners when using the Minerva skin.
- The network tab in the web developer tools shows a successful request to Special:BannerLoader, but the response is not injected into the page.
