Indicator elements <indicator> are not shown in mobile view. They are not part of the html source code.
Yeah, MobileFrontend's Minerva skin needs to have support for them added (assuming that it is wanted, I'm not sure if it currently displays FA icons and the like). I completely forgot about it. Example similar change for MonoBook: https://gerrit.wikimedia.org/r/#/c/163558/
Prioritization and scheduling of this bug is tracked on Trello card https://trello.com/c/gb3kNPJJ
