Open emacs -nw (or on MS-DOS, just emacs.exe); then, type:
C-h n C-x h
observe that the text representing icons within the left margin is also
highlighted. Now, move the mouse over a link on a line that contains
such an icon: the mouse face will be displayed one column to the left of
its proper location.

I see this, both on GNU/Linux and on MS-Windows in the -nw session,
but I don't think this is a bug.

This I cannot reproduce on MS-Windows. (I don't have a GNU/Linux
system with a mouse-capable TTY, so I cannot try there.) Or maybe I
don't understand what you mean by "link on a line that contains such
an icon"? By "links" do you mean symbols quoted 'like this'?
Strangely, not all of the links are highlighted with mouse-face, only
some. And I cannot understand what makes different instances of a
link behave differently.

This doesn't happen on X frames.

Yes. Perhaps this bug is specific to the MS-DOS build; msdos.c's
variant of tty_draw_row_with_mouse_face seems to lack special treatment
for the margin area that is present in term.c.

Or maybe we are witnessing different manifestations of the same bug.
Thanks.

It does if you customize icon-preferences to use only 'text'. The
default icon on GUI frames is an SVG image, which defines its own
background color, so the region-face background doesn't show.

Could be. Patches welcome.

You mean, you see all of 'quoted' symbols show as links on GUI frames?

Considering this, and that:

I just installed a fix for this, I'm closing this bug. Thanks for
shedding light on this.
