Looking at the misc/terminfo.src changes in that patchlevel, I see that
you added xterm+focus to several terminfo entries that had used
xterm+sm+1006, which is logical and in line with the NEWS entry.
However, tmux got changed the other way around: it already had used
xterm+focus, and you added xterm+sm+1006. This is the diff hunk:

That seems to be not really intended and should likely be reverted,
given the issue at hand.

There is no VTE involved in this case, I reproduced the problem in
xterm.
