No, I didn't remember (and still don't actually, tho I now see the
corresponding comments and #if0 in the code).
But that change only affects the decision of what we consider as the
boundaries of a chunk of invisible text (so it makes no difference in
the present test case where there is no such ambiguity).
Once those boundaries are found, we do use Fget_pos_property to decide
which boundary to go to.

There are 2 odd behaviors:
- point adjustment doesn't bring us to position 3 after C-n
- M-: (point) has the side-effect of bringing us to position 3
My guess here is that after the M-: command, at the end of
command_loop_1, last_point_position refers to a position in another
buffer (i.e. in the minibuffer), so it thinks there was a movement and
hence re-runs adjust_point_for_property, which this time gets it right.
