That's right.  And that's by design (didn't you test and greelight the
patch of bug#78106)?

Look again.  It's used for ElDoc, there's a

   (funcall cb blurb)

further down.

This would break the current uses ElDoc . And if I follow your
intention, it would still be wrong, as if 3 actions were present it
would say sth like:

  mouse-1: execute code actions at point
  (2 more actions available)

which doesn't make sense.

In my opinion, there is nothing to do here.  The richer blurb is only
meant for the ElDoc outlet, because that points to a specific non-mouse
binding which will immediately execute the singleton action at point or
offer a menu of all actions.  The mouse bindings always offer the menu.
