To reproduce:
- visit wikitech.wikimedia.org (you can currently use https://wikitech.wikimedia.org/?country=US to fake being in the US for the WLM campaign)
Expected result:
- no banners, since wikitech is not shown in any of the campaigns at https://meta.wikimedia.org/wiki/Special:CentralNotice
Actual result:
- See a CentralNotice banner
We know this is banners targeted at Wikipedia projects, since it happened yesterday with fundraising banners which are only ever targeted at Wikipedia. I did fix fundraising banners to hide them if loaded on Wikitech, but other banners can still be shown.
We could do the same as T270308: API portal showing Wikipedia CentralNotice banners and hide CentralNotice banners on Wikitech. But it would probably be better to add it as a proper target site if possible
