MediaWiki 1.33.1 (34871e5) PHP 7.2.24-0ubuntu0.18.04.1 (apache2handler) MySQL 5.7.27-0ubuntu0.18.04.1 ICU 60.2 Elasticsearch 5.6.16
Steps to Reproduce:
Have browser language set to a different value than the user preference in mediawiki.
Log in to a mediawiki instance.
Actual Results:
The popup obscures the edit tabs, and doesn't allow these to be selected. Eventually, after a longish wait, the popup will go away.
Expected Results:
The (IMHO unnecessary) popup should not cover essential parts of the UI.
