AFAICT, there is something of a ping-pong game going on between multiple
bugs whose solutions conflict with each other. 

1. The bug was first introduced with the following commit:

3. However, the problem resurfaced with the following patch, which
effectively reversed the previous fix.

    org-agenda: Fix bug when showing the new time
    
    * org-agenda.el (org-agenda-show-new-time): Ignore invisible
    text when inserting the new time as a text property.
    
    * org-compat.el (org-move-to-column): New argument
    `ignore-invisible' to turn on `buffer-invisibility-spec'.
    
    Thanks to Marcin Borkowski and Karl Voit for reporting this.

The timing of the patch leads me to believe that it was a solution to
the problems outlined in this thread.

So, in summary, it seems we have different bugs whose solutions have
thus far conflicted with each other.
