bug#18712: 24.3; IELM fails to move point in a working buffer that is also displayed

[Trevor Murphy <trevor.m.murphy@gmail.com>]

Hi, list.  I just noticed the following.  If I start from `emacs 
-Q', then go:
 1. M-x ielm RET
 2. C-c C-b *scratch* RET
 3. Type `(goto-char 1)' at the ELISP prompt and hit RET
 4. C-x 4 C-o *scratch* RET

Then I see the *scratch* buffer in the other window with its point 
on the first character in the buffer (the first `;' on the first 
line).

However, if I reverse the order of steps (3) and (4) above, again 
starting from `emacs -Q':
 1. M-x ielm RET
 2. C-c C-b *scratch* RET
 3. C-x 4 C-o *scratch* RET
 4. Type `(goto-char 1)' at the ELISP prompt and hit RET

Then I see the *scratch* buffer in the other window with its point 
unmoved (still at the start of the second line after the initial 
scratch message).

Is this a bug?  And, if so, is it reproducible given the info 
below?

Thanks in advance.
