Okay, thanks for the test case.

FWIW, I'm not sure this is worth fixing, amazingly enough.  There
might be other circumstances where we will have such effects (meaning
that the cursor isn't at the locus where characters are inserted).
The bidi text editing is one such case.  (I can describe the details,
if you are interested.)

Fixing this might have an adverse side effect of breaking the rule
that the cursor is displayed on the character *after* point.

What I think _is_ important is that the user should be able to
understand why does this situation happen.  I think your case
satisfies this condition.
