It is, only, in conjunction with `org-protocol`, that kill-ring and Wayland-clipboard get out of sync.

Not in some general case. General case is fine.

But in the case of org-protocol, as described in the original post and not present in the excerpt you quoted, they do get out of sync.

To summarize again there are two things that are happening:

After doing `xdg-open "org-protocol://store-link?url=URL&title=TITLE"`.

The string "URL" is pushed into Emacs kill-ring.

But, this very string "URL", is not inserted into Wayland clipboard.

That was the first thing, string pushed into kill-ring, but not pushed simultaneously, into Wayland clipboard.

Now second thing: from that point onward, the other way around is broken. (And that is the part that is really annoying.)

[Then] I mouse-select a string in Firefox, or any application not Emacs. I verify the string is indeed in Wayland clipboard, I paste it in Firefox, or in the terminal (not Emacs).

Now I do `C-y`: this later string is not pasted, even though it should have been. I do `M-y` to see if I can find the string in the kill-ring: I can't find the string in the kill-ring.

What, instead, is the string at the top of Emacs kill-ring: the string "URL" (from the initial org-protocol action).

So Emacs has now stopped inserting strings from Wayland-clipboard into Emacs kill-ring.

No matter how hard I try.

The labor-intensive workaround:

Now what I do is copy a string inside Emacs using `C-w`.

Then, I verify if I can past it in Firefox: I can. It really is in Wayland clipboard.

Now I copy a string from Firefox into Emacs: it is not broken anymore, until the next time I use org-protocol, at which point it gets broken again.

And now it really is also present in Emacs kill-ring.
