bug#70019: 30.0.50; bookmark-set: fringe icon (again)

[Dani Moncayo]

Recipe from "emacs -Q":

1. Open the Emacs manual [C-h r].
2. Set a named bookmark in some line of the *info* node [C-x r m f o o RET].
3. Go to another *info* node and repeat step #2 there (with the same
bookmark name).

When I do this, I still see a "bookmark" icon in the fringe of the
first *info* node (wrong, since the bookmark now refers to another
place).

Also, if I delete the bookmark (from the "*Bookmark List*" buffer), I
still see the icons in the fringe on both *info* nodes.
