For GROUP_CONCAT, "\n" is interpreted as space

I'd like to have each of the concatenated results in a new line (results format HTML). I use something like that:

(Group_Concat(DISTINCT ?result; separator = '\n ') as ?results)

However, both \n and \r are interpreted as space, while using any normal character works fine.

As I remember getting what I expected in dbpedia with \n, let me also add that I'm currently using 07.20.3214 version of VOS (in case it's a matter of configuration).

(added later) This is in response to the suggested usage of <br>. Here's a query for dbpedia, which works with \n but with <br> it doesn't:
