There's a Firefox bug <https://bugzilla.mozilla.org/show_bug.cgi?id=1815733> where this was happening in Outlook web, which they claim was fixed in 129, but I still see this in Guacamole in Firefox 133. Maybe someone from the Guac team can parse the explanation there and see what's up?
On the client side, if you search for this, you may see advice to use about:config and set dom.events.testing.asyncClipboard to true. But this is a bad idea <https://bugzilla.mozilla.org/show_bug.cgi?id=1815733#c18>.
