Administrators often use templates for their block reasons, for example {{TMOblock}} which shows https://en.wikipedia.org/wiki/Template:TMOblock to the blocked user. On mobile, however, all they see is the string "{{TMOblock}}", which doesn't convey any useful information. It would be great if this message were parsed before displaying it, so that it conveyed the same information.

If template parsing isn't possible (since this is tricky on the client-side), it would be great if it could at least contain parsed links.

Also note that only administrators and higher can enter block reasons, in case there are security concerns with displaying unescaped messages in the client.
