Copy/paste under "System-wide Autotype" doesn't work on XFCE

[gravelld]

I have installed Goldwarden using Flatpak and logged into Bitwarden's default server. I can list all my entries.

I have configured a hotkey in xfce to open the Autotype dialog, as described here:

dbus-send --type=method_call --dest=com.quexten.Goldwarden.autofill /com/quexten/Goldwarden com.quexten.Goldwarden.Autofill.autofill

I can search and find entries. When I press the down cursor to find the entry I want:

I have tried Ctrl+P to copy the password. The Quick Access window disappears, but when I paste into another app nothing is pasted.

I have also tried Ctrl+U for the username, but that doesn't work either.

Is it something to do with the clipboard and the Flatpak sandbox?

I see a number of these messages from the daemon, but only when I scroll up/down, not when I try to copy:

[WRN] [15:35] [Goldwarden > Websocket] >>> Invalid message received, length too short
