I already forked the ui-repo, found the correct file to fix it and even found the place where I should add a query to the search form to search only for communities if you start searching from the communities page.
But then I saw that this change is already done in that file. I double checked the HTML on my instance and there it’s broken. I checked the history of the page and see it has been fixed 18 hours before I started looking into it.
All my hard work for nothing.
Lesson learned, always pull and branch from main.
Actually I was working on the main and that’s where I saw it being fixed :D
