Clipboard Doesn't Work Between Host and Container Properly.

[zebra-f]

To be fair I don't know what's the best to report this issue.

Describe the bug
I can't paste from the host's clipboard into Neovim running inside an Ubuntu container. I have also tried using $ xclip -o, but the same issue occurs. There are exceptions: whenever I copy something from Discord (*F), Gimp (*F), Spotify (*F), or Steam (*F), it will be available inside the container. Both $ xclip -o and Neovim can access this content. However, copying from other applications, such as Firefox (*F), Easy Effects (*F), Neovim (separate process, *F), KWrite, System Settings, or Konsole, doesn't show up inside the container.
I have also tried copying with Ctrl+C and Mouse.
Xclip shows this error:

$ xclip -o
Error: target STRING not available

(*F - installed via Flatpak.)

Whenever I yank something in Neovim running within the container, it will be available in the host's clipboard, so there is no issue in that direction.

Are you using Podman, Docker, or Lilipod? Podman.
Which version of Podman, Docker, or Lilipod? Podman 5.3.1.
Which version of Distrobox? Distrobox 1.8.0
Which host distribution? Fedora (41) Kinoite, KDE Plasma Version 6.2.4, Wayland.
How did you install Distrobox? Came preinstalled.

How can I fix this issue?

Solved.
In Fedora container, when installing Neovim, it asks for permission to install dependencies:

I noticed wl-clipboard, installing it via apt in a Ubuntu container solves the issue for Neovim (not for xclip).
