Hello, Andrew.

For what it's worth, it works fine for me with the emacs-25 branch in
X-Windows (more precisely, XFCE).  (Shift selection doesn't work at all
on my Linux virtual tty.)

I have `isearch-allow-scroll' set to t, and I search for a word in
Isearch, which is found.  I then type C-S-right just once, and the next
word after what had been the highlighted search region gets highlighted
for me (in grey).  The Isearch operation is now terminated.
