[BUG] org-agenda-clock-cancel does not update agenda buffer [9.6.15 (release_9.6.15 @ /nix/store/5hl68vr85cagmwaycqy652r2g2isjcyq-emacs-29.2/share/emacs/29.2/lisp/org/)]

[z]

After clocking into an entry (org-agenda-clock-in) from an agenda
buffer (such as org-agenda-list), the entry is highlighted with a face
(org-agenda-clocking).  When the entry is no longer clocked in, e.g.,
by clocking out or marking it DONE, the org-agenda-clocking face is
normally removed.

However, org-agenda-clock-cancel is the exception, as it doesn't
update the clocking entry's appearance.  Pressing r (org-agenda-redo)
fixes the appearance.  I suspect org-agenda-clock-cancel just needs to
call org-agenda-unmark-clocking-task.
