The translation from mouse-1 to mouse-2 (controlled on the user-side by
mouse-1-click-follows-link) depends on the presence of a follow-link
property or binding (see Elisp manual for details).

Because the place where the mouse-1 click happened has a `follow-link'
property or binding which tells Emacs that this is a place where mouse-1
could be turned into a mouse-2 (depending on
mouse-1-click-follows-link).

So you should try and figure out why there is such a `follow-link'
property or binding at a place where you don't want the
mouse-1-to-mouse-2 translation to take place.

And yes, the implementation of the feature was changed, so your problem
was apparently masked in previous versions of Emacs and is now exposed.
