If you attempt to create a region by dragging the mouse in a
never-before-focused window, then the region isn't shown until letting
go of the mouse button.

Steps to reproduce:

emacs -Q
C-h f help RET
Click and drag the mouse in the help window

This doesn't work in the pretest, but it did in Emacs 24.5.
