As discussed in this T194139 ticket, deepcat is not enabled on all wikis at the moment. We should inform the user of this potential issue.
Add warning to the infotext of the deepcat keyword.
I'm a bit confused because on commons i only find this icon but the current OOUI icons use this alert icon. So I guess preferably the latter in orange but if that's not possible in time for the deploy then the one already on commons will do.
The link in list.
- The warning text appears in the infotext of the deepcat keyword where advanced search is enabled.
