Add wl-clipboard to Flatpak

[DPTJKKVH]

Overview

When copying a password with CTRL + C the password is only cleared after the countdown if the KeepassXC window is in focus. If it is out of focus, the password remains in the clipboard indefinitely.

Steps to Reproduce

1. Click on a database entry.
2. CTRL + C to copy the password
3. Highlight a different window than the KeepassXC window. (e.g. a text editor)
4. Wait until the "clear clipboard after" timer runs out.
5. CTRL + V in the different window.

Expected Behavior

No password should be pasted since it should have been cleared form the clipboard after the timer ran out.

Actual Behavior

The password can still be pasted.

Please reopen this issue. I tried it with the 2.7.9 Flatpak version and the issue still persists. Video below!

This isn't our bug. It's a bug/feature of GNOME on Wayland. We try to work around it by calling wlcopy directly instead of through Qt. Unfortunately we can't do that with Flatpak.

[DPTJKKVH]

Understood. Why is the Snap version still on 2.7.8 on the stable branch though? Is that deliberate?

[droidmonkey]

The snap owners have our update held up in some manual review. The whole process with snaps is broken.

Thank you for answering my questions and maintaining this project despite the many challenges it poses. Fully understood and I will move on to the PPA then.

[droidmonkey]

@DPTJKKVH you may have to install wl-clipboard if you haven't already even with the ppa.

@droidmonkey

fyi: I didn't need to install wl-clipboard for the clipboard clearing to work as intended. (I verified in synaptic that it isn't installed.) Just in case that information is useful.

[droidmonkey]

I'm going to try to add wl-clipboard to the flatpak itself, see if that works
