There's no guarantee any clipboards softwares will
even agree on what is on the clipboard. Some of the
clipboard items could be automatic translations of
things submitted by the sourcing application. And
Wayland being a latecomer, of course it's going to have
to do weird shit, to get a name for itself.

Firefox supports all three serving options, as would a Chromium.

   Wayland, Xwayland (temporary X11 option for older programs), Xorg (original X11 still available)

A person doing testing, has to find two clipboard managers (Wayland one, X11 one), have three login options,
to do some tests. And even then, who knows whether the answer is based on
hard reasons underneath.
