Error with fzf-lua picker, fzf-tmux profile

[franco-ruggeri]

🐛 Describe the bug

Using fzf-lua with the fzf-tmux profile as a picker, I get this error when using either :Obsidian backlinks or :Obsidian tags (and selecting a tag):

[Fzf-lua] fn_selected threw an error: ...hare/nvim/lazy/fzf-lua/lua/fzf-lua/profiles/fzf-tmux.lua:15: assertion failed!
