I tried with i3, seems to work correctly (all tests with a floating
window, since that seems to be a prerequisite for stickyness under i3):

(set-frame-parameter nil 'sticky nil) has no effect
(set-frame-parameter nil 'sticky t) makes the frame sticky,
and (set-frame-parameter nil 'sticky nil) makes it unsticky again.

I tested Emacs 26 with both Lucid and GTK builds.
