It seems like tmux support was added in 26.1, specifically by this commit:

commit bd34a6c73f2651e9413b138cf98240faf559c790
Author: Mark Oteiza <mvoteiza <at> udel.edu>

    Add term/tmux.el

    Since tmux version 2.1, new tmux terminfos are shipped due to oddities
    with xterm and screen terminfos.  This is simply a duplication of
    term/screen.el with screen -> tmux.
    * lisp/term/tmux.el: New file.

I'm therefore closing this bug report.  Please test Emacs 26.1 or later
and report back if it still doesn't work as expected.

Best regards,
Stefan Kangas
