I cannot reproduce this.  I see neither of the problems you describe,
and nothing like the screen recording you posted.  You don't show the
details of your platform and build, so maybe it is something specific
to that (macOS, per chance?).

Can you post a detailed reproduction recipe, starting from "emacs -Q"
and showing all the settings and commands you have to do to reproduce
the problem.

Thanks.
