On https://da.wikipedia.org/ the Sitenotice won't close when you click on the close button, in Danish called [Luk].

The problem is the same in all browsers and seems to affect all users, whether logged in or not. Also other Wikipedia languages seem to have this problem, the Bosnian Wikipedia also has a sitenotice at the moment that won't close.

The problem was first reported on August 8, 2020, 11:46 (CEST) here.

The sitenotice appears on any page and some users find it annoying. For logged-in users the sitenotice would normally not reappear for a month when closed (a cookie is set), but this doesn't work at the moment.
