Clicking an item's copy button in Firefox does nothing: the
clipboard keeps its old contents, and selecting the text and
pressing Ctrl+C by hand is needed instead.

Suspects, given the machine's history: the Wayland clipboard
and the data-control protocol (see the 1Password flatpak case,
where the sandbox's Wayland proxy stripped data-control), the
clipboard persistence plugin holding or racing the selection,
or focus rules around the popup the button lives in. Needs a
reproduction against a plain page first to split Firefox from
the desktop.
