Clipboard is set up and everything copies just fine, but doesn't paste into LibreWolf?

[writeblankspace]

I set up the clipboard and echo g:clipboard gives me wayclip. On the KDE clipboard widget, it shows me the stuff I copied.

But for whatever reason, the stuff I copied never pastes directly into LibreWolf. It can paste anywhere else though, such as Kate or Obsidian. When I paste the text into Kate and copy it from there, it pastes just fine into LibreWolf.

I don't think this is directly a nixvim issue. I have no problem pasting into firefox.
Can you try this config?
