On the latest release (9.3.7), I am running into an infinite loop when clocking
in a blocked task if `org-enforce-todo-dependencies` is set to `t`.
The (manual) call stack is:
org-agenda-clock-in
org-agenda.el:9760 org-agenda-change-all-lines
org-agenda.el:9391 org-agenda-finalize
org-agenda.el:3879 org-agenda-dim-blocked-tasks
The while loop on line 4012 is infinite in this case.
The problem is because when `org-agenda-finalize` is called, the region is
narrowed to a single line. Then in `org-agenda-dim-blocked-tasks` the function
`(move-beginning-of-line 2)` is called to advance the point, which does not
work when the buffer has a single line.
In an earlier version, the command `(forward-line)` was called which moved the
point to eol when the buffer had a single line.
