Descripción

When accessing the issues page, we get to see a list of the most recent issues, and also a form in order to conduct a search. In this form there is the field "Project", which is presented as a field that shows a list of projects as you type by completing the typed letters. However, what I get on Abrowser 88.0 (32 bits) on GNU/Trisquel 8 is a Javascript error beginning with:
