    The problem is that the sit-for runs redisplay before the
    post-command-hook, so the cursor type is displayed based on the
    previous buffer position rather than the current position when moving
    the cursor upwards.

Isn't there another redisplay after running post-command-hook?
How come it doesn't show the new cursor type?

Isn't that a bug?

Anyway, the other problem cases just reported are certainly bugs.
The right thing to do is to make every redisplay detect when this
has changed, and DTRT if so.  It won't cost much time either to
implement or when running.  We should not even consider suggesting
a work-around for a bug we can fix.
