Yes.  I verified that the problem you describe happens in Emacs 27.2,
but not with the current master branch.

No, you misunderstood the discussion.  It says the bug was fixed on
master, not on the emacs-27 branch (from which Emacs 27.2 was
released).

However, if you build your own Emacs, you should be able to apply the
patches from that bug and rebuild Emacs 27.2 with those changes.
