bug#29173: 25.3; pulse-momentary-highlight-region is not visible when region is active

[Yury Bulka]

To reproduce:
1) Select some region in a buffer
2) eval:
   (pulse-momentary-highlight-region
     (region-beginning)
     (region-end))
3) No visual feedback is appearing

By contrast, evaluating something like:
   (pulse-momentary-highlight-region (- (point) 5) (point))
results in the area around point highlighted as expected.

The steps were tested in emacs --no-init.

This has now been fixed in Emacs 27 by giving the overlay used to pulse
a higher priority than the default.
