Mostly because the locator for the author link changed, from
"span(:author_link, class: 'flow-creator-simple')" to "span(:author_link,
class: 'flow-creator')"

There still was a "span(:author_link, class: 'flow-creator-simple')" on the
page though, the author to whom the user is replying, but hovering over
that element does not (right now) trigger the display of Talk/contribs.

Fixed with https://gerrit.wikimedia.org/r/#/c/98000

I really like Firebug, it's the only page inspector I know of that will let
me search the HTML easily, and has a lot of other nifty features.
