Oh, you are right, as I see now, the i tags don’t get closed.

The output is: (tested with curl)
<td>
<i class="fa fa-angle-down"></i>
<a data-csrf="US9sIjgJOn1jDRsPCjcyJlhSKAhIJgAA9YUxHDMN6HxjCtUMkciqgA==" data-method="delete" data-to="/link/28" href="/link/28" rel="nofollow">Delete</a></td>
Adjusted the code to the following, ant this works:
<%= link(content_tag(:i, "", class: "fa fa-angle-up"), to: "/link/moveup", method: :post) %>
<%= link(content_tag(:i, "", class: "fa fa-angle-down"), to: "/link/movedown", method: :post) %>
So.. apparently “tag” is not usable for tags? is this normal behaviour?

tag/2 is a low level function which does only create a “tag”, aka <name {attrs}>. It doesn’t concern itself with the notion of opening/closing tag.

Thank you everyone! Going to mark @LostKobrakai his answer as the solution.
