You could try without passing (dedicated . t) as alist element.  The
manual says

          The dedicated flag (*note Dedicated Windows::) has a slightly
          different meaning for side windows.  When a side window is
          created, that flag is set to the value ‘side’ to prevent
          ‘display-buffer’ to use the window in other action functions.
          Its value persists across invocations of ‘quit-window’,
          ‘kill-buffer’, ‘previous-buffer’ and ‘next-buffer’.

So a dedicated flag that does not equal 'side' might cause the problem
here.  If it persists, I can write some code for 'display-buffer' so we
can find the offender.

We could try to paint the window dividers accordingly.
