bug#24372: 25.1.50; After losing focus, cursor is hidden when moving point

[Philipp Stephani]

I've tested this with a GTK build on GNU/Linux; other toolkits and OSes
might also be affected (but terminal mode doesn't seem to be affected).

emacs -Q -eval '(setq blink-cursor-delay 0.0)'

Move point around in the scratch buffer (e.g. press C-b a couple of
times): the cursor stays visible, as it should be.  Then put the mouse
focus on a different GTK window (not Emacs window), put the mouse focus
back on Emacs, and move point again: the cursor is hidden, making it
impossible to see until you stop moving.
