When visiting http://localhost:8888/w/index.php?title=Special:Watchlist&watchlistview=feed&filter=all you'll see that no user icon appears next to the username of the editor despite the icon HTML being there. This leaves an empty gap which is confusing to the reader.
This tasks requires that MediaWiki core and MobileFrontend extension are installed and properly setup.
User icon is not being rendered before username when displaying list of edits by users, but rather, there is a space before the username which is suppose to be a user icon.
The result of this problem should be a user icon to display beside(to the left) each username as expected when listing the edits by users (watchlist).
