bug#38288: 27.0.50; Rectangle kill/copy/yank stopped working

[Pankaj Jangid <pankaj.jangid@gmail.com>]

* Steps
  1. set mark at one point
  2. goto another point slightly lower right side of fist point to cover
  some text to kill/copy
  3. C-x r k OR C-x r M-w
  4. Try to yank at some other point

* Result
  Some previously normally killed text is yanked instead of recently
  rectangularly killed one.
