I don't know what applications behave the same.  I tried different
editors that I could find (namely LibreOffice Writer and xed)
and all they extend highlighting of the selected region
to the window right edge, not to EOL.

Also I looked how other applications extend diff blocks, and e.g.
GitLab extends diff background colors to the window right edge,
not to EOL, for example,
https://github.com/emacs-mirror/emacs/commit/3d6075e3ee8c447f8974b37007a1b1ae1af8917c

However, no other application extends underlines to the window edge
as Emacs used to do, this was a plain bug that this change fixed.
