Found when verifying T215117: [S] Don't focus on search input when displaying search results in Special:Search.
- As an anon user or a user with MediaSearch set as default, go to any page on commonsw wiki.
- Click on the search icon in the Search text box or type there - Special:MediaSearch
- Special:MediaSearch page will be displayed - the input field won't have a focus, so a user is not able to start typing.
Note: That MeidaSearch behavior is different from Special:Search. If a user with default Special:Search (or by entering Special:Search in the input field) goes to Special:Search page without any results, the Special:Search page will display the focus in the search input field.
