I didn't think it was particularly relevant, as the behaviour was
reproducible with the 'tmux split-window -t <n>' command alone, however I
have included below anyway.
Unfortunately the tmux server where I was able to reproduce the problem has
segfaulted, so I might have to put this on ice until I can reproduce it
again.

This is the key binding, for e.g. I would use a sequence like Ctrl-A, N,
node10{1,2,3} <enter>:
# prompt for hosts to connect to, open a new synchronized window with
horizontally split panes for each host, supports brace expansion
bind N command-prompt -p hosts: 'run-shell -b "bash -c \"~/lbin/nw %%
>/dev/null\""'
This is the script, called "nw" for new window:
#!/bin/bash
#
# 2018-07-10 only synchronize panes if there are multiple hosts/panes
#
# use 'ksh -l -c' to invoke profile for push, etc.
# abbreviate host name list by identifying common prefix and comma
separating suffixes
abbreviated=$(
echo "$@" | awk '
{
min=length($1)
for (field=2; field<=NF; field++) { if
(length($field) < min) min=length($field) }
# find longest common prefix
for (prefixlength=1; prefixlength<=min;
prefixlength++) {
prefix=substr($1,1,prefixlength)
for (field=2; field<=NF; field++) { if
($field !~ "^"prefix) {mismatch=1; break } }
if (mismatch) break
}
prefixlength--
printf "%s%s", substr($1,1,prefixlength),
substr($1,prefixlength+1)
for (field=2; field<=NF; field++) { printf
",%s",substr($field,prefixlength+1) }
printf "\n"
}
'
