Eric,
I'd like to add that X.org has the concept of two "clipboards," the copy buffer
which in many GUI programs you put data into with Ctrl-C after making your
selection (or through a context menu, e.g. Edit/Copy, Edit/Cut, etc.). It also
has the concept of a selection buffer, that gets populated whenever you
highlight (select) text with your mouse (with no other keyboard or menu events).
This selection buffer you paste with middle click usually.
Now, depending on your window manager (WM) or Desktop Environment (DE, sounds
like you're using GNOME), you can combine these buffers into one (essentially
telling your environment to put selected text into the copy buffer, which gets
populated whenever you select text). That may also be at play here (I'm not
sure what GNOME defaults to for this nowadays).
Typically highlighted text from mouse events is handled solely within your local
terminal emulator. tmux shouldn't have any bearing on this usually unless
you've enabled mouse mode (you've witnessed firsthand how difficult that can be
with X11 Forwarding). You stated your problem seems to be with irssi in a
remote tmux window; you're likely bitten by the common problem of URLs being
wrapped within irssi (so you can't just click the link to launch the URL in your
configured web browser; the URL will be incomplete). I haven't used irssi in a
long time, but weechat (another CLI IRC client) you can issue the '/window bare'
command to load the channel buffer into a pager (like less or more) where the
terminal emulator sees the entire URL (i.e., not broken up by wrapping) so you
can merely click on it rather than copying it somewhere else and navigating that
cumbersome way. I'd see if you can configure irssi similarly. I also use a
similar feature in mutt/elinks to solve the same problem in email.
IIRC, irssi was missing a lot of features the last time I tried it, a lot of
common IRC functionality had to be added manually by the user.
My $0.02. Hope this helps.

Dealing with 3 clipboards here... even ignoring the tmux clipboard, the X
vs Gnome (terminology? - the one you refer to as the *real* system
clipboard) clipboard confusion has been a bad Linux user experience
problem for a long time now. Are you aware that you can usually use
middle-mouse-click to paste from the X clipboard directly?
