Hmm... That's clearly a problem.  I can imagine some reasons why we do
that, but I'm not sure they're good enough.  This probably deserves
a `M-x report-emacs-bug`.

Another approach is indeed to consider the input-method insertion as an
"atomic transaction" and hence postpone remote updates until that
transaction is completed (or at least to do that if the remote updates
touch the affected text area).  But indeed, that can be problematic (with
some input methods, a single char can terminate the previous entry and
start the next at the same time, so it's possible to be "in the middle
of an input-method insertion" for quite a while).
