There's no up-mouse-N events in Emacs, AFAIK.  There's only
down-mouse-N events and mouse-N events; the latter are generated when
Emacs internally sees the Nth button pressed and released.

What issue is that?

When you do what you describe, Emacs doesn't generate the C-mouse-3
event because it never sees the button released with the Ctrl
modifier.  This is expected and documented.
