That has no effect for me on Fedora 28 which I believe uses mutter as
the wm. Similarly running it multiple times has no effect.

Running

(set-frame-parameter nil 'sticky t)

once or multiple times results in a sticky frame, as expected.

Iʼll see if I can try on my KDE-based Ubuntu later. Thatʼs based more
directly on X, unlike my Fedora machine which is using XWayland.
